I have been dumped by about 6 or 7 therapists (not sure the exact number) so I know the drill well, haha! Any decent therapist will realise that they are obligated to refer you to another more appropriate therapist, if they feel that they do not have the skills to treat you. So ring him up and request that referral ASAP! That way you come out of it with a positive - maybe the new T will be decent.

That "closure" stuff is BS. It is just an opportunity for them to get the last word in, really. Don't worry about that. Just remind him that you are entitled to a referral and everybody's happy.
