I'm being forced to go to a psychologist tomorrow, and while I want to live alone, I hate telling people anything. A while back I dropped-out of college and went back to my parent's, where I pretty much refused to go outside and leave my room when anyone's around. I know that I won't tell the psychologist much of anything and that the sessions are essentially going to be a waste. Even if I want to tell him anything "useful", I would either lie about it or wouldn't be able to communicate it correctly...
I'm not sure what I should do.
Are you happy with how you are? if there's anything that you aren't happy with just bring it up, you might as well make use of the psychologist. If saying it aloud is a problem type it out and take it with you and just hand it over, emphasising the fact you find it difficult to talk to people about these things.
I recently began seeing a therapist and I felt the same way you did going into it (similar situation as well). I must say that it is worth trying to open up a little, despite your concerns that you would lie (presumably out of embarrassment) or fail to communicate correctly. Chances are that the person you are going to see is adept at dealing with people who may not be able to articulate their feelings- he/she will lead you along to becoming better at it. Just give it a chance, hopefully you'll quickly see how (for lack of a better word) theraputic it can be.
