Im going to echo some of what Alex and Kyle have said as I think theyve made very good points.
Youre already in the process, youre getting things moving which is good. And 2 years? Think of things 2 years ago, youve probably made alot of progress since then, and that wasnt even that long ago. Just hold onto the hope of how much things will be better in another 2 or even 3 years!
I was in a very similar situation to you. So much I had to go through - 7 different counsellor/professionals, different Drs and clinics, each giving me hope and then letting me down. Being told I could be seen at 15, at 16, then being told they wont even touch me till Im 18. At the time, the wait felt like honestly, the slowest time has ever passed. I had to go through the rest of school and 6th form, looking either androgynous (which I hated) and people ask me what I am, or male, with the humiliation of people using "she" around people who use "he" then people just stop talking to me and start talking about me.
Hell, I worked a job for 6 months where some of them thought I was female (by the name I wasnt allowed to change yet) and all those who were hired after me, thought I was male. How I managed to keep this going I dont know! :p
But basically, I know the hell youre going through. But honestly, the other end makes it worth it. Ofcourse itd be great if we didnt have to go through any of this, but, the suffering is worth it for the reward
