I'm sorry!
Did T explain why? When do you see T again?
Sometimes I write out my feelings..things I'd say to T. How canceling on short notice made me feel. You can either send it to T, share at next meeting, or not send at all.
Sometimes I wrap myself up in a big comforter and either sleep, read or watch TV.
If I'm feeling inconsolable, I remind myself that I usually will have a different (better) attitude after a good nights sleep. I might take half a Benadryl to go to sleep.
Do something nice for yourself- have a swim or a nice soaking bath.
