Pre-transition, my emotions and life experience, I would describe as the following: I constantly felt like there was some sort of thin fog hanging over my life.
Basically, your default state as a person is something that you aren't supposed to notice, right? You're simply supposed to be you, doing the things you like to do, feeling the emotions you're supposed to feel that come with the various ups and downs of life, working, seeking after pleasurable things like friendship, love, following your artistic passions and needs for self-expression, right?
Pre-transition, it felt like there was a fog hanging over all of this.
I experienced joy, absolutely. My favorite joyful things pre-transition were being able to walk alone through a beautiful natural setting, the feelings of love and trust and closeness that I had with my romantic interest at the time. And yet something always felt... off. I was constantly bothered by this feeling that I couldn't fully express myself, and that my hormones and my body were constantly in conflict with how I saw myself.
Like, the way that I saw myself was as someone who was cute and nice and non-threatening. And yet people treated me like an adult male. Which means that they gave me this sort of respectful treatment, one where they hold me off at a distance with respect rather than looking down on me and smiling, and they didn't understand that I wanted to be close to people, and that I liked cute things and sweet things and being adorable and beautiful things. Every single social interaction with people had this broken-reality feeling to it, where it felt like people were always fundamentally treating me like someone that I wasn't, like they couldn't see the real me, the person that I saw myself as, because my body and gender didn't match the feminine self that I felt like.
Body dysphoria was constantly intruding into my life. I hated my body hair, I hated that I had this big blocky frame, I hated that I couldn't look beautiful and couldn't look feminine and couldn't be in a body that was smooth and soft and shapely and feminine. I hated having facial hair and a deep voice. I would basically constantly be looking at my own body, feeling those feelings of "wrongness" with it, and then looking over at women's bodies and realizing that that was what my brain was expecting to be there. I wanted smooth skin like them, I wanted a feminine body shape like them. And this also manifested itself in interfering with my romantic life. I was in a relationship with a girl pre-transition. And when we were intimate together, she was in complete and total bliss, enjoying every single second of it. And at the same time, I would constantly be dealing with this feeling of "what the heck is this erection down there? That feels so wrong," and wishing that I could have a vulva instead, that I could feel the same feelings that she was feeling, that feeling of a body being completely flush against your romantic partner, able to squeeze them and hold them with your body without that weird feeling of a body part poking against them like that. I pined for the feeling of strong hand caressing my soft smooth hairless body, the feelings of what someone with a vulva feels during physical intimacy. So even though I loved the snuggling and the calmness and the emotional intimacy so much, I couldn't enjoy it physically, because the act of intimacy with this body felt wrong.
My emotions felt wrong all the time. I constantly felt irrationally angry, and I hated myself for it. There were many times where I was watching a sad movie or had a tragic life event happen, and my brain kept telling me that it wanted to cry, it wanted to release that sadness and let it all out. And yet it felt like there was a cap on my emotional expression. I couldn't cry. I couldn't laugh like other people laughed. I couldn't enjoy life like other people simply enjoyed life, and I could see it. Other people enjoyed their social interactions with others, enjoyed their sex-drives, enjoyed intimacy, while I felt like I was constantly fighting against it and constantly felt like a slave to it. No matter how hard I tried, I always felt like I was constantly fighting to get people to see me as I saw myself, constantly fighting against my body and wishing that it was female, constantly dealing with the depression that comes with knowing that I couldn't be them, that I couldn't just be the person that I saw myself as. I survived just fine, and I tried my best to be as happy as possible, but again, it felt like I was living in a fog.
Post-transition, I feel normal.
There never was a cathartic release where I said "YES!!! I MADE IT!!! I'm a woman now!" and danced for joy and celebrated and my life was happy from then on. Now that it's been 3 years I don't even really remember having "transitioned." In my mind, there's still continuity. I'm still me. It's just that the more time goes on, the more I look back on the things that used to be a serious hindrance to my quality of life and I realize that wow, I don't feel those things anymore. Life is simply much more normal now.
When people talk to me, it's ME that they're talking to. When I have emotions, they finally feel like my emotions again, happy or sad. As I'm following my passion, that disease called dysphoria interferes with me much less often and I'm simply able to be, to enjoy life, rather than having it constantly interrupting. My body finally feels more like my body. (Not completely there yet, though... dysphoria doesn't completely go away.) My sex drive finally feels right instead of feeling like I'm a slave to it or it's wrong. I'm finally so much more able to feel normal, to feel like I'm free to be me and do the things I want to do without dysphoria constantly getting in the way. That's the feeling. Being normal. Finally being able to take life and your own sense of self for granted
The way I see being trans, it's a medical condition. It's something that hinders your ability to enjoy life, to feel connected with your body and connected with your identity in the same way that everyone else is. Transition is not about "changing" from one thing into another. It's simply about being the person that you've always seen yourself as.
TL;DR:
Pre-transition: was always trying to feel "normal" and yet was constantly derailed by feelings of fundamental "wrongness" and this feeling that a sort of fog was blunting my life experience.
Post-transition: doesn't really think about it anymore, I'm mostly just living my life.
