Thanks for your replies.

Yeah, you're not the only ones to tell me that... but I'm still unsure about what the problem is (me? the therapist?)
I technically could try some other T... but I should ask my parents for that (I'm 18). My fear is to look like a spoiled child who just can't trust other people to them.

As for the phone thing.. well, it doesn't really bother me, but yeah, it's kind of rude. Especially becauase he doesn't even ask permission, or apologize. He also smokes sometimes (with an electronic cigarette) but he asks permission for that.
