I am sorry for your estrangement. Not only are you not alone, I'd venture to wager that estrangement is the rule vs. the exception. My own story, briefly, my wife loves me but thinks that my being gay means I am broken. My two adult sons want nothing to do with me, and we were very tight before my coming out in December 06, talking several times a week. They have chosen fundamental christianity over me. They are certain they know me better than I know myself...familiar?
I'm not sure what's more damaging, people who straight out (pun intended) reject you? People who pretend "you" don't exist? Or, my all time favorite, those who "love the sinner, but hate the sin." Can't you just feel the "love?" Well of course you can, that "love" helped you "crash and have a breakdown."
You say you are feeling "anger" right now. Sounds like you are working through the mourning process. Sad that, but often true. I read everones entries and just sigh with sorrow, because each is expressing a death in their family (our own). Sort of. The truth is, most of us were never allowed to live in the first place, and we are at varying stages of discovering what it means to simply be alive. I am sorry you have to fight for your life, but you are indeed in a life and death struggle.
Glad you are here. You do have family here.
