Dear Jessica,
Not transgender, but a cisgender Lesbian, yet I know what it means to be hidden.
Called my oldest brother, after years of no contact, and his son in law picked up the phone, and when I said I was his sister, he was amazed, as he was told he had no sisters! Interestingly, his wife and step daughter kept his wife's ex-husband's name, instead of taking his name!
Have no contact with the rest of my relatives (cousins, aunts and uncles), but I consider my T/LGB friends my family!
Sadly, my T/LGB cousins live on the other coast (Portland, OR), with no contact. Also, I have a bisexual (really Gay) brother in a miserable marriage, for fear of the treatment I and his T/LGB cousins received.
A few years ago, I went to a family reunion, and saw how my family treated a second cousin's wife, who is an American Black, and her children, who are racially mixed, and the husband of another second cousin, who is a motorcycle club (not gang) member.
They are not my family, you (T/LGBs) are my family!
Your sister,
Monica
