Hi
Well, first off I wanted to say that, for myself, your post was hard to read because of all of your 'slang' or whatever that was.

I just pointed that out because I almost stopped reading it halfway through because of it, and I would hate for you to lose good advice because you chose to write the post that way.
So, you said that people watch you while you are in public like there is something wrong with you? Is it possible they are looking at you because you look like you are having so much fun at whatever it is you are doing? You didn't give much detail as to what you normally are doing when people are watching you, other than stating that you were all cheery and stuff. Maybe they watch you because they find you interesting to watch?

Anyway, I wouldn't worry much if you can help it as to why people are watching you. I think we all feel like that from time to time (or maybe more often than that). People like to watch people...I know some that will go to the mall or other public places just to do that.
Anyway, sorry I wasn't more help, good luck!
