Yes, I definitely get that separation anxiety feeling. I'm allowed to email my t, but she'd like me to restrict it to 1 email per week if/when i'm able. So far, i usually have to leave a couple of messages per week -- on a super bad week, maybe 3 emails. But i strive for just the 1 email as much as i can.

In between sessions, i use distraction and some of the coping skills my t has taught me. Sometimes, i'll write letters to her but not send them. I also try to bring up in my mind the sound of her voice or something she's said to me recently, to try to hand onto the connected feeling.

It's really hard to wait a whole week to see her again when something major is going on in my life, but i just try to keep myself busy as much as possible and hope the time goes by fast.
