Hey man, I'm sorry your going through such a bad time now, I know the feeling, I feel like I'm stuck too, even though I have T,(I'm not on it yet though, it's just sitting on my dresser) my mom and grandmother just don't want me to get on it and telling me how much worse my life will be if I get on it and that's why I'm kinda waiting to get on T, but I'm also afraid of some of the side effects too, that's why I'm waiting also.
Do you have a counselor to talk to or Friends or any family members that are supportive?
Think about this... once you turn 18 you can get T. You can do whatever you want, you won't need your parents approval to get it. I don't know how old you are so I don't know how long you would wait to get T, but in the meantime maybe you could find a gender therapist or a counselor to talk to so by the time you turn 18, you can get your T letter and get on T. I haven't talked to a gender therapist so I don't know how that works if maybe you can get T earlier than 18? Maybe if you and your parents talked to a gender therapist or a counselor your parents would see that getting on T would be a good thing and see that you would be happier.
