I've got a hypnotherapy session tomorrow morning for my anxiety for when she comes. Then the lady suggested a block of sessions over 4 weeks to help me cope with everything better. I think I may take her up on that.
A bit more advice on the upcoming visit in case it helps reduce your anxiety--
1) You don't have to initiate or maintain any conversation with her. 2) If it's quiet, have something to do, e.g. a book to read. 3) If she starts chatting, imagine you're a polite but busy coffee barista or cashier. 4) If she asks an easy question, answer. 5) If she asks a hard question, "I'll think about it." 6) If she vents, listen and validate. Review the thread on validation. Practice it on others. 7) If she's abusive, shut down the conversation
Big goofs would be 1) acting emo--e.g., making rash decisions or statements out of grief, 2) peacocking--e.g., dressing up, chatting with her, and holding books to impress her. It looks desperate.
