I definitely feel the same way. I've even told my T that I could stay in his office for 8-10 hours a day, every day. Depending on what's going on in my life and what I'm working on with T, sometimes the time flies by between sessions and I "forget" about my next session. Sometimes I'm watching the minutes tick by so slowly to the next session. I go twice a week and sometimes even that's not enough.

I would recommend keeping busy with work/school/family/friends, whatever is in your life now. With time, it DOES get easier and you DO find that balance between being obsessed and constantly thinking about therapy and getting on with your own life. There will be days when the thoughts are overwhelming about the next or current session, and days when the thoughts are hardly at the front of your mind. Hang in there, you'll find the right balance.
