I'm in a weird situation so I'll do my best to explain it. About a year a go I came out to my Mother about being transgender, I wrote a letter and left it for her to find. She was very supportive and nice about it however when she wanted to talk about it I just started to seize up and couldn't talk. After two weeks of awkwardness where I couldn't bring myself to talk about it with her I just said that it was a phase even though I knew it definitely wasn't. So now a year later I have decided that I need to come out properly otherwise I will get nowhere. My only problem is that I have a lot of trouble talk to people, be it face to face or over the phone, so I'm not sure if I can pluck up the courage to do it again. I honestly have no idea how I did it the first time, I guess because it was a letter made it easier which is why I have no problem talking online about things. I have also been thinking that it will only be a couple of years before i'm old enough to live on my own and see a gender therapist without parental permission, though the same problem of not being able to talk to people will still apply and I doubt I will be courageous enough to seek one out and talk to him / her.
I know I sound like such an idiot but I really want to come out and transition because I want to be who I am on the inside but I just feel so nervous and scared to do so. What should I do?
