Hey guys.
Finally found the courage to make an account on this site, I am new to this but just wanted support/advice I guess?
*This will probably be long but I'll make it as short as I can. I don't know any transgender people so bare with me

I will put questions in bold so you don't have to read it all if you don't have to*
Edit: I'm from the UK 
I did actually attempt to come out as transgender (FTM) at 14, had a letter prepared and everything actually but my mother found my web history/bookmarks on a transgender website I had set up on my laptop [using a male name] and I came home from school to lots of shouting/arm waving etc. She was shouting 'so you want to be a boy do you?' and 'why me, why does this have to happen to me?' ...so naturally I never did give her the letter due to that reaction. She actually spent a good while crying too and this made me feel so guilty. I do have other family but if I saw them in the street I probably wouldn't recognise them and vice versa so we were really close.
At 16 I came out to her as lesbian because for all my life I have always loved women, I thought this is who I was etc but even that label wasn't right to me.
Time passed...feeling even more uncomfortable with my body. I've always had quite masculine energy and face anyway so 80% of the time I'd be referred to as sir, young man etc. I've been watching youtube videos and looking up articles for the past 6+ years and identify with being a Transman. I used to buy myself male clothes and wear it in the house when my mum wasn't around then got older - didn't care and wore lots of tracksuits etc to hide my figure.
I have a mixture of male and female friends but I hate being grouped with the 'females' because it doesn't feel right. I felt the same way at school when in sports class they split the groups up by gender. Going to changing rooms was an issue for me too. We had compulsory swimming at school and I hated it. Love swimming....just not the outfits and segregation...I want to swim again but I can't ...not looking like this, anyway.
For the moment I feel uncomfortable:
-My body doesn't feel right and never has.
-Being referred to with female pronouns
-Being treated/viewed as a female
-Restrooms ...don't even start me off on this one..I drink very small amounts throughout the day at college now because I don't want to use the restroom...I only use it in emergency situations [once a month]. I feel so wrong and embarrassed using them - as if I'm some sort of weirdo..you know? As far as I'm concerned I don't belong in there.
I work in retail too which makes me being seen as female even worse. The uniform is pretty much unisex but my name badge displays my name and unfortunately for me it is very female name - you couldn't even question the gender of someone with my name.
-Customers come in and say to their kids 'give this to the lady'...I hate that. Then some of the kids will be like 'Mum...that's a man [That's great] except my name tag conflicts that and everything gets all awkward.
-When guys come in I start to feel jealous etc especially when they bring a girlfriend with them or have male products in the basket.
-Worst is when people call me 'love' or 'darling' or 'sweetheart' etc.
The issue is now, at 20, nearly 21 I feel that I should just go and seek guidance from a GP or whatever...I'm moving out and starting University in September so it will be interesting and a challenge. In the past I was way too embarrassed/nervous/anxious to do it. In a way I really want to go to the local university but then I feel if I move area at least no one would know me etc? Also I need a transfer from work because where I am everyone talks about everyone's business..even just little things plus it's a tiny store and I'm familiar with all the locals etc now. I know this is a possibility elsewhere but that's not the point. I was initially a little excited about uni after finally figuring out what I want to do...but my feelings have literally swamped my mind and I am no longer interested/excited about anything else...just feel so sad..I don't leave the house unless I have to and I find myself wanting to reach out to my mum but at the same time I won't ..so I lock myself in my room most days unable to talk to her too much and getting angry every time she speaks to me..even if it's just to ask if I'm okay

I'm almost living three lives right now...one at home with my mother (don't express myself as much as I want - my mum just thinks I'm a butch lesbian)....one when I'm out and about (I deepen my voice to talk to people) ....then one at work where I have to talk to customers etc and it's obvious I'm 'female'... almost like the 'telephone voice' people have...kind of girly and not quite right.
Questions:-Is it a case of seeing a GP who will then refer me to a gender specialist/clinic? Or something?
-How does the process go? (roughly) I know it's different for others etc.
-Can I go to just any old GP? Or would I have to seek one out?
-For those FTM or even MTF how long did your transition take?
-Did your body disphoria change over time?
-When did you come out to friends/family? What were their reactions like?
-Specifically, what were your parent(s) views on it? Immediate reaction and/or reaction during and after transition?
SORRY IT IS SO LONG!
