My own reply:
Pretty much what Zinnia described there sums up my life up to this point

!
Especially this sentence hit a nerve:
"Feeling like a veil or glass wall separates you from the world"
I've literally felt that. And said that. Whenever I'm misgendered or thought of as a woman I feel like the other person just perceives me 'wrong' as if he was looking at me through a distorting glass. And I'm somehow trapped inside that glass - like I know I'm me, but the outside world is unable to see that, and it's totally frustrating.
As a kid I wasn't allowed to express my boy side with clothing or toys and was a depressed and emotionally abused child in general, so I was a total zombie. A depressed kid. My mom was super controlling and I learned I wasn't allowed to state my opinion on anything or even have one, so I completely dissociated myself from my true emotions, feelings, thoughs, opinions and ideas... at least regarding gender. The best example of that would be that I got two awful gifts for my bday once, from friends: a hideous mermaid statue and a truly repulsive Pocahontas poster. I absolutely hated both but felt I wasn't allowed to express that, so my mom put the poster up the wall and placed that statue on my windowsill... And I had to look at the items every day for goodness how long - but zombied out.
From an early age I learned I had to endure unpleasant situations and things I didn't like - but could do nothing about it. So just dissociated myself. I mostly lived my childhood inside my head in a fantasy world. And even irl I escaped to playing characters in uncomfortable situations - a form of dissociation too.
I was full of anger - but wasn't allowed to express my anger at all. My mom tried to make it like i hadn't a separate identity from her at all. She loved to dress us up in similar clothes... and when strangers commented on how we looked alike it made me cringe.
But I learned to emotionally separate myself from my emotions, anger, dysphoria, uncomfortable situations etc. like it wasn't happening to me. Or by completely blocking it out of my mind. I felt I had to endure, endure, and endure. Endure but not live.
I kept on doing that in adult life when I was denied access to treatment at 16. That was the final blow in a row of many, stretching throughout my childhood. I felt I had had enough and would never again allow anyone to make decisions for me, including succumbing to that screening at the trans process. So I never went back.
That hurt like hell and I had a mental breakdown for not getting treatment - but applied my old coping method for that too: dissociating. I became totally numb and zombie-like and tried to pretend it didn't really matter. Like it was a no big deal. I felt they destroyed my life, but determined to live, I kept on enduring, hoping I could afford top surgery someday on my own.
Eventually that led to me dissociating myself from being a guy, from being trans, from life, from people... Not wanting to interact with anyone like this... And envisioning a lonely future for myself where I would achieve my dreams, yes, but only interacting with my spouse. I felt I was unable to have genuine contact with people, like this. So I totally dissociated myself from even wanting that in the first place.
My true feelings on things come up as strong physical sensations like cringing in the stomach or feeling 'acute wrongness' about something, like misgendering and being treated as a woman. I have very strong reactions to things like my deadname and that I absolutely refused to use that anywhere, ever. But I dissociated myself from life like all that didn't matter, really.
My no 1 and main coping strategy has always been, 'if you can't change it or do anything about it, don't think about it'. And that applies to my gender and anything dysphoria enducing. It doesn't really change my chest if I get anxious as hell about it, does it? So I can use that time doing something else, more productive. But also that is a form of dissociation. It's interesting to ponder whether things like that are dissociating behavior, mental strength, or positive attitude? Or perhaps all three?
But thinking like that does distance myself from even dysphoria. At times I get thoughts like, 'is this really that bad?' 'I can cope like this through life just fine, right?' 'Am I really even trans...?' And then my TRUE feelings come out as strong physical reactions, extreme anger, and cringing. And also as gender euphoria and/or sense of 'normalness' when I'm treated as a guy.
But I could really say I'm a master of dissociation when it comes to my gender and life in general...! I'm so used to feeling numb, zombie-like, suppressing my anger and true feelings, used to general unpleasantness all around me - that that has become my natural state. That I don't even expect much else or expect my life could dramatically improve with things like T. I know either way I'm gonna survive and continue on living (coz I'm not suicidal - far from it!), but so used to feeling sucky and numb that I can't really picture much else.
Now during 2018 my reality has starting to shift a bit though... And I'm learning things I thought were 'out of reach' for me or impossible are indeed possible...! The biggest change being that when I legally changed my name in February, I've felt normal and happy ever since. And noticed some nasty noise that's been there all my LIFE just shut off, just like that. I had become so used to it, I didn't even notice its existence before

. And now I've gotten so used to feeling like this, better, more normal, more like me, and like I'm actually LIVING MY LIFE NOW - that my whole life up to that point now feels like a distant dream, like it never happened.
I now have a peculiar feeling I'm actually LIVING, like ALIVE. And able to take concrete steps to affect my life and change my future. I'm still so used to dissociating that I'm almost scared of living and being true to myself, though ofc always tried to be as much as possible. But for the first time I have a strong feeling I'm living MY life now.
During my whole adult life since that 16 I've had this strange feeling I'm not living, like at all. I only exist inside my own head, and have no connection to the outside world. Like not even the human species. And even my physical abode, my body, does not reflect who I am.
I still have these feelings that my mind and body are totally separate, but still kinda 'me'. Like I know the real me is my mind and in my mind I'm a guy. But then also I'm physically female and I have to 'like' myself physically too, to some degree at least to not hate myself's guts. If I connect too much with my physical body, I fear I'm losing 'myself' as a guy. And if I remind myself too much how female my body actually is (and what others all the time see) it makes me question my sanity. So I just cope with blocking that out of my mind, being on my computer as much as possible, chatting with people online... forgetting what I actually look like.
I managed to cope through life with periods of not binding (!), being treated as a woman, residing in this physical form. and if I think about it too much, I become depressed and anxious, so I don't.
Like in DID, somehow I'd like to reconnect my mind and body... Only my mind keeps playing these tricks on me by questioning if I should do that by accepting my female form or by transitioning and trying to change it more male. It's almost like... as if my physical self was my 'alter' saying 'I'm you too, don't change me!'...! And I want to love myself, and also my physical self/body... but my mind/inside is a guy that just keeps hating everything in it. It's a battle between how much I hate my physical femaleness depending on what perspective I take.
If I take a 'I'm me, inside my mind=a 100% guy' perspective, I hate everything in it and everything feels wrong. If I take 'I've survived all these years looking like this, it's not that bad' perspective I can enjoy my body and sex and exercise and moving it, and kinda liking aspects of, it not most of it! My breasts I don't ever like - but sometimes I feel 'wrong/guilty' about mutilating my 'healthy body' via surgery. If I take a perspective of 'I know I'm trans and just happened to be born as female but it's not that bad coz I can change most of it via HRT and top surgery' I can connect to most of my body as 'myself', like pretty much all of it except for breasts. I can see my legs and arms and the wholeshebang as 'me' with just minor details to tweak with T. But it's a constant battle between extreme dysphoria and general acceptance within me.
Also the fact I'm able to dissociate dysphoria away makes me question my real emotions and ability to make rational decisions for myself. Like 'do I even know my true thoughts on anything?' Did the mind learn to hate the body and dissociate from it? Do my body and mind make a complete human being, and I should take my body into consideration too...? Or is my body just a lump of flesh and the mind the master who controls it? In that case, am I really 'born in the wrong body' and trapped in it or by it? Like an actual guy in a female body? That is quite an excruciating thought. So I'd rather think my body is also 'me' or part of me, at least. And precious as such. Or am I just a human being, a female-bodied individual, who likes to present as a guy in the world? In that case I'm unique and can even embrace my uniqueness as 'trans' and as a 'guy with a vag'. But I battle between 'everything is wrong' and 'everything is okay except for breasts' - and then I question myself for that. Why can't I accept my chest then?
But if I drop all the dissociating and coping... I become a mess. If I think about my body too hard, I don't wanna exit the house. And if I think about this body situation too hard, I want to chop my tumors off myself! And get very, very desperate and anxious.
So I mean... for trans people... some amount of dissociation is required, right? Just to survive!
