Even in the best of circumstances with wholly supportive families we get flack. Why? Because they love us and don't want us to eff up our lives. They want to make sure that we are sure, that we're not harming ourselves by taking hormones and having surgery, etc. I dont' think a trans person exists whose family 100% embraced the news that they were transitioning without any questions, naysaying, or what have you.
I'd say that many of us had families that said and did things when first learning the news that hurt us, made us question why we came out, and may have made us want to slink back into the closet. But many of us also have families who came around, who supported and still support us.
For a lot of people it means educating themselves on something they really don't want to think about. Heck, I went through the same process and it was MY life! I went from the privileged position of straight white women (yes, I know people will argue that women aren't privileged) to gay male. First off, I had NO connection whatsoever to the GLBT community. At all. Other than having acquaintances who were gay or lesbian, none were in my close circle of friends. Call me clueless. And then, my views of trans people were totally warped based on the media when I grew up. Freaks!!
I had to educate MYSELF before I could transition. Now, not only am I trans, I'm gay, and a member of a group that traditional values people would call sexual deviants (never minding the fact that I'm celibate!).
So yeah, it is a lot for family to digest. Hang in there.
