I see my T once a week (minus vacations)... (she would like to see me twice a week, but my insurance would never approve). We have had 40 sessions now over 9 months time. There is no planned end date for me. My T and I are in this for the long haul.

What's a lot? Idk. I'd worry more about if you're getting what you need out of therapy rather than how long you're in therapy.
