It depends on how my week is going. Sometimes, I have zero contact inbetween sessions. Sometimes, just a single email. This week, I needed some help, so it was a few text messages back and forth, and two emails (all yesterday...it was a bad day) and my T offered a phone call if I needed it.

Generally, it's just a single email between sessions. I worry about bugging my T, but she's reassured me that she will let me know if I'm over stepping any bounds.
