I agree with QM here... Him being unhappy doesn't mean he's angry. It just means that he doesn't like to see you suffering. You might be a difficult client, but seriously, there are very few people who aren't. If you don't want to take meds, then that's ok. It's his job to help you find ways to feel at least a little better.

The questions you mention are difficult questions. I never had an answer to them. If I did, I'd not need to see them (therapists) in the first place. When do you see him next?
