I was a disaster. LOL. Thin, athletically inept, intellectual, uncomfortable in my own skin. And I, too, had gotten picked on a lot since I was yay high.
Then I got into music and became an extroverted rock performer. It was a very liberating experience that opened up a lot of doors.
But off-stage I was still very uncomfortable, insecure and disconnected from my own physicality. It took a long time for me to realize exactly how much physical space I occupied... very strange sense of separation there.
Fortunately, through working with a friend of mine who's a certified personal trainer and exploring various physical, mental and spiritual modalities on my own in the years since then, I don't have that problem anymore and the elements gel a lot better now.
Not sure I'd call myself a "jock" a la the name of this site, and I certainly still have a lot of geek characteristics (but those are fun and I don't mind them)... but I'm definitely not the bumbling, uncoordinated disaster I was in years past.
At 32 I've grown into my own skin quite nicely, I think. Of course that skin (particularly around the waistline) occasionally does its own growing, LOL, as I indulge in certain guilty pleasures and/or step away from exercise, etc., intermittently. But hey, I'm a human and do the best I can. It's certainly far better now than it was back then.
