My T encourages out of session contact, more often than not I get so shut down during session that Emails are how she learns the most about me. I'm getting better at being more engaged in session, and thankful she let me use Email as a way to get there. So, just to answer your initial question, I would contact T (by sending an Email) whenever I felt like it, whether I felt good or bad, or had something to say or not. I don't contact her constantly, however. There were times I'd simply write her just because I knew she'd nag me for not hearing from me between sessions.

Based on the other posts here, if you EVER feel so low your well being could be in jeopardy, please contact your T. I use Email, as it's not intrusive, she can check/respond whenever suits her. If I have something quick, or something I want to make sure she sees, I will text her. I've never called. But if the situation warranted it, I imagine I would call her.

You have us, TWF, and some of us currently feel just as you do. You're not alone. Use this place as a distraction if you need it....It seems like there's always someone here around the clock, so you're never completely alone. Hugs to you!
