oh my gosh...I wish I could articulate the way I am feeling as well as you do! Just THINKING about my family and "family stuff" in general, and my anxiety level shoots up from a regular, daily 2 to a dizzying freekin' 8.
I think you expressed perfectly how you are feeling. And IMHO, I don't think it's weird or freakish or crazy at all...in fact, taking into consideration what you've written, it sounds completely apropos.
I would venture to guess, your T would WELCOME the discussion, too, because it's probably one of those "doors" in T that once you cross through, you come out on the other side feeling so much better
Hugs to you,
Rose
