I had no idea you had that problem. I never thought an assertive guy like you would have any trouble socially, or care what people thought of them. In fact, there have been a lot of times I've been jealous of people like you, because it seems from my perspective like you can get just about anything you want.
You seem so different from me on the surface... but I guess you're not totally. I didn't get insulted much growing up, I just worked to be ignored, and was successful. But I'm sometimes sad for the same reasons.
I know everyone else is down on you for caring what other people think of you, and seeming kind of "sad"... but to me, you just seem more human now.
