One thing I have learned from my experience is that I am happier being rejected/accepted by my family as myself, instead of pretending to be someone more 'appropriate'. Family should love you for who you are without stipulations. If you are dependant on your mother this might be a lil more difficult of course, It sounds like you have a close relationship with your mother which means that she might be able to work through any issues she may (or may not) have.
It's worth noting that I have come out the other side with less people to spend xmas cards to (at least for now) but that the relationships with people I still have feel less hollow and more rewarding to me.
I totally agree with @ivan - an anti-androgen sounds like a good option for you and it isn't (in Australia anyway) too hard to get at all. Anti-androgens are also prescribed for helping prevent baldness & prostate cancer. Meaning (again in Aus) you don't need a letter from a psychiatrist to start taking it and is, for the most part, reversable.
For me it had a larger effect on my depression than the anti-depressants and mood stabilisers I am on.
Best of luck hey.
