Sounds like some holiday doldrums, provoked by relatives. I was in the doldrums yesterday. Today I feel better. So this feeling won't be endless. You have done so much hard work and accomplished much in therapy (and in your life). None of that has changed because you are feeling down right now. I understand about wishing you hadn't emailed your T. I have sometimes felt that way about things I have told my T in session. But at my next session, he is never pushing it back at me and wishing I hadn't told him that. He is very accepting and welcoming of what I share. I think your T is the same way.

Hope you feel better soon.
