I know things can seem pretty hopeless. I've been there. I even decided that transitioning was impossible for me so I'd better get used to the idea of being a "man" for the rest of my life. Cue 20+ years of trying, frantically, to fit in as a man, to make my family happy, to make my friends happy, and all the while thinking that I was a fraud, a sham, and altogether worthless.
All because I could not accept myself.
You are on a cusp in your life; different paths stretch before you. What I can say from 20 years down the line is that there is nothing to be gained from repressing yourself and burying the real you. It ends in misery, shame, and disappointment. For some, it ends in death. For me, it did end in a kind of emotionless walking death. I have so many years I could have *lived* but chose instead to trudge along.
Whether you transition or not, whatever you do, do it for *you* and your life. Everyone deserves a chance to live, to be happy. Please continue to explore. Save money and get out on your own if you need to... or start now, looking for sliding-scale therapists in your area so you have someone you trust to help you chart your course.
I'm telling you what I wish I had heard at your age. I probably wouldn't have listened to me, but here's hoping you do... you are already ahead of where I was. You are reaching out.
