Jessica is right. If your mom absolutely won't bend, the best you can do is just try to use the time the best you can. I waited only 3 years to start T, and now I'm awaiting surgery...both are equally painful. I just keep myself busy, you know? Do my best in school, worked hard (when I was still employed), when I was younger I had some hobbies like rising my bike and playing around on the computer. It still sucked, but those years did pass, and yours will too. 🙂
I also try to view my situation differently. Like, when I feel bad about having to bind my chest (cause other guys don't have to worry about hiding boobs), I trynot to say that to myself. I try to say to myself "ok, it's just an extra little inconvenience, having to grab something to cover my chest." It's a lie to myself, cause obviously my chest is a huge source of dysphoria and is related to my transsexualism, but, it's enough for me to believe it and to hang on to knowing that surgery will happen one day.
