Taka showed me how to work the irc chatroom last night, but I was already feeling ok by then. Getting up out of bed, walking around, and poking through the forum helped.
I think it's fear of the unknown, fear of this foreign territory, not fear of anything specific happening. I also think some of it is not really fear, but I can't pinpoint what it is, exactly. Shame?
Wait. Yes. It's shame.
Yesterday my husband brought up some more reasons why he didn't think I was "a man" (I'm not a transman, I'm transmasculine) after I shared some thoughts I'd repressed. His solution to this issue seems to be "teach her to accept that she is cisgender with a few variant traits."
I was also thinking about another thread I started about my therapist, in which he sounds much less suited to my needs than I previously thought. I'm not sure how I expected him to help me accept myself when even he won't accept that I'm transgender.
Probably those things triggered the intense discomfort I felt last night.
Thanks for your concern, LordKAT and Ms Grace.
