SoSadMom,

A lot of people here have had the same problem. How long have you been going to this T? For me I don't think going more times a week wouldn't have helped. I just needed time to acclimate to a totally new environment. I can totally relate to your comment about going blank. This happens to me a lot. I have a lot of things floating around in my head before and after a session, but as soon as I sit on the ugly couch they just move out of reach. All I can say is that things are starting to get better.
Here is what I've tried and seems to help a little bit.
1. writing a private journal.
2. reading and expressing stuff here on PC
3. Listening to music especially stuff that seems to connect to my emotions. I've even create a special playlist to listen to while I'm waiting for my appointment. This seems to help me relax and connect a little bit.
4. continually remind myself that I'm doing the best I can.
5. In the beginning I wrote a letter to my T expressing that I am having some difficulty.
6. My T accepts email and letters, but doesn't communicate with me between sessions. I sometimes send her what I can't seem to retrieve during a session. She then response to it in the session.

My communication skills are slowly improving and I am hopeful that eventually talking will get easier.

Just keep trying different things, your T will see that your trying and work at it from her end too.
