Am I jinxed?

I think I am jinxed. I used to have this superstition that if I really wanted something, something will happen and it might not happen. When I fall down and hurt my knee or sprain my angle, instead of thinking its fine its nothing, I used to think, O its a ligament tear or the bone is broken, fearing that if I am optimistic, I ll end up being screwed. :) But that was in the school as a kid. And I had long lost those feelings along with my innocence. But now I think I am on my way bak to being paranoid. Anybody there?
