You said a lot of things that you don't want.

You can't pursue a negative very well. If you try, all you're doing is running away. That doesn't lead you anywhere.

Figure out what you DO want. Define it clearly and in great detail. Focus all of that energy on getting it.

You'll quickly find that all of the other stuff - people's opinions, how they look at you, what you think they expect of you - disappears once you've started pursuing what's important to you.

Trust me, I know. When I was in my 20s, I spent 30 hours a week at the gym, took every supplement on the shelf, spent way too much time caring whether or not I was interesting, attractive, desirable, etc. When I finally stopped giving a crap and just set out to get what I wanted out of life, everything got better.

I mean everything.

I tried suicide when I was younger. I used to cut myself. I would get so depressed that I couldn't get out of bed. I hated myself (and thus, I hated everyone else.) I was diagnosed with bipolar disorder, mood control disorder, and borderline personality disorder (anti-social PD, I think they call it now) and my therapist told me he was very surprised that I hadn't succeeded in taking my own life by the time I was 18. =| That I lived long enough to become his patient was an accomplishment, I suppose.

All of that disappeared into the ether virtually overnight when I finally stopped caring so much about everything else and turned an inward eye. What do I really want? How do I get it? When you pursue that positive line of thought with all of your being, you have no time or energy left to waste on worrying about other people's opinions.

EDIT: Oh, and I used to have abs and maintain something like 4% body fat. People thought I was an MMA fighter. Now I'm pudgy as hell and still happier than I ever was when I was in shape. I also still get dates with very attractive women (which I used to think was impossible without a perfect body.) I literally lost NOTHING when my six-pack disappeared lol. I had a very unhealthy fixation on my appearance and I'm glad I finally learned that it really doesn't matter so much in the grand scheme of things. There's a very good chance that your looks aren't a key factor in achieving whatever great thing you decide you're destined for, so try not to worry if those couple of extra pounds won't go away.
