I know.
No, I'm not in therapy. Well, yes, there are things people are visibly okay with, or like them about me (and they tell me), but still...
I admit, you have some good points here, although it doesn't really fit my situation (I really am told that the way I act is pleasant also by people who my relationships don't go well with). I tried a few therapists who are the best in the area. One of them didn't say much (nothing meaningful) and one other got to know my personality, didn't see anything wrong with me and literally said, "I don't know what to tell you."
