I personally am so messed up that I need 2 times a week. And T agrees... Otherwise I lose connection and get crazy abandonment issues with lead to SI, etc.

There is nothing set in stone though. Things can change. You might ask what your T normally does. It also might depend on your $$, your "diagnosis", your time, and your T's time. Also, it might depend on how many client's T has with the same problems, whether they can deal with more time, etc.

Good luck
