I think it is just a normal thought; lots of people here and in general use that phrase I think, talking about themselves; wpos :-) is in the urban dictionary even and if you Google it you get pages and pages of hits.

That you were thinking about it instead of listening to what your T was talking about is normal too I think, it was just more compelling to you to explore your negative feeling than change subjects at that time.

What I do when I have thoughts like that about myself is point out to myself how "lame" and vague the argument is. There's no examples, no proof, and the entire argument is based on the ethereal unknown groups of people, like "society" and not on anyone specific.

I would be your friend, because I like you. You would not have to "do" anything for me because I would just enjoy your company, sense of humor, quiet mannerisms perhaps. Who you are is not about what you do.

What you do just helps people (sometimes really dense people who can't appreciate another without props of "things" they have done) confirm their opinion of why they like you. Think about it; if I like your sense of humor, you might just laugh at all my jokes, even the lame ones, and show me you enjoy me too. You might tell good jokes or have a way of putting things when we talk that is amusing to me. None of those things are you consciously doing something for me? They are just you being you.
