Hi hj,
Sorry to hear that you didn't hit it off with the therapist. If you don't have the choice of choosing a different one, you are probably best to open up as much as possible to the one you have. Could you ask for sessions more often than once every 2 months? That doesn't seem enough to me.
If you can keep from harming yourself I don't think the therapist will put you in a hospital against your will. Did you tell him that you don't want to go into hospital? If you really have a problem with the therapist, are you able to discuss this with your doctor? She/he might be able to arrange an alternative.
I really hope that you stay strong and do well at your next therapy session.
