So I'm a bad guy.

I genuinely felt sick to my stomach later on reflection when I recalled just how nice she was being, and my glaring, total disregard.

Being nicer isn't some earth shattering change in persona. It is the little things you do that make others believe that you are nice. In your post above, you said that you glared at little kids that waved at you. Next time, just smile back. When someone compliments you on something try saying "Thanks" in a nicer tone. You don't even have to look at them. I know it sounds cheesy, but it is really the little things that go along way in how you get along with people. I agree with the other posters that when life gets hard for someone, it can become more difficult for that person to get along with others. It is a natural response. The fact that it bothers you is proof, like Traveller87 said, that you aren't a bad guy.

Jam it back in, in the dark.
