Reddit mentions of True Selves: Understanding Transsexualism--For Families, Friends, Coworkers, and Helping Professionals

A big thing is to make sure she feels secure. It takes a long time as a trans girl to really trust someone. We are extremely vulnerable to having our heart guts ripped out by casual statements, pronouns, and being cornered in a bad situation. Be proactive about taking it slow. When I first transitioned I was no good at knowing the subtleties of body language, phrasing and stuff like that. As a result I guess I threw off a lot of weird signals to friends and acquaintances. Be aware that if you think she is signaling you to go ahead, it might just be a miscue. Don't rush anything unless she is telling you in no uncertain terms that she actually wants to go ahead.

Aside from that I would recommend you start reading books and browsing through forums. Books like True Selves and Trangender Explained for those who are not are good starters. Then you can start reading some biographies as well. It certainly isn't something that you can learn in a few weeks though. Take your time and be careful.

My father is a Catholic and very strong in his faith. When I first came out, he didn't want to accept it until he had talked to the priest. The priest reassured him and they talked about it for a very long time. My dad accepted me because of the kind words of a priest. Maybe suggest to your mother to talk to a few priests about it on how she should deal with it. A "good" priest will tell her that God loves all things, and so should she, and not to show hatred or prejudice against any given group. (Maybe you should talk to her priest first, so you can get an idea of what he would say to her? Maybe ask the priest to talk to your mom?)

Thank your sister for the support she does give, and tell her it means the world. If she feels appreciated, she is more likely to offer more support. Same with your dad.

I'm not so good with brothers... my brother and I aren't very close, and he isn't very accepting of my transition (he's not vocally opposed either though). Maybe try giving your brother some reading material on the subject of transsexuality (True Selves)[http://www.amazon.com/True-Selves-Understanding-Transsexualism-Professionals/dp/0787902713] is an awesome book, even if it is a bit old. My mother bought like 20 copies of it and gave them to all of our family and close friends.

Also, do you know if that movie is on Netflix? :D

Honestly, it's been 2 years and they are no closer to accepting you. If you've been constantly fighting, it ain't going to change unless they realize they're going to lose you. Logic won't magically convince them because they will always come up with one excuse or another.

This stuff probably won't change their minds, but for shits and giggles, I'll paste it.

"The Transgender Child" is also a good book for parents. Under $20 off amazon or whatever.

True Selves is another http://www.amazon.com/True-Selves-Understanding-Transsexualism-Professionals/dp/0787902713

"Families in TRANSition: A Resource Guide for Parents of Trans Youth" is a PDF they can download.

Recent article on youth (which at 18, you're not) - maybe the suicide statistics would help convince them, but then again... lots of people would rather have a dead kid than one of those queers, they're just too pussy to admit that. http://www2.macleans.ca/2011/08/12/when-boys-would-rather-not-be-boys/

PFLAG can be helpful, but they don't sound like folks who are willing to go to one.

If they've threatened you with violence, that doesn't bode well (but record these instances with dates, etc on your cell or whatever, if you're in the USA, they can basically deny you FASFA grants/loans until you're 25 unless you ask to be declared independent, however you need a lot of evidence to do this.)

I'd personally fuck with them and have them blow $30,000 on a reparative therapy camp (and then write a book about my experiences) but I'm kind of odd and masochistic.

If books are on the menu, True Selves is a good one, though slightly outdated http://www.amazon.com/True-Selves-Understanding-Transsexualism-For-Professionals/dp/0787902713
