I'm sorry that you're going to lose your grandfather. I can imagine how awful it is when a loved one doesn't recognize you.

Can you use T1 for support about your impending loss, since she's still your T and she allows emails?

I would be extremely hurt if my T didn't acknowledge something like that in an email. Sometimes rules are meant to be broken. "I'm sorry "would have been sufficient." I think I missed why you can't resume twice weekly sessions if she won't bend her rule. My T told me to TRY not emailing but she didn't forbid it. I do it when I need to. I'm really sorry because your T 2 sounds so good otherwise. I'd suggest talking to her about it again. Hugs!
