It is often a common habit of thinking what others think about you. I had the same problem before. But then we all have idols, and if not, we should make ones. And then, thinking about what those idols think of what you did in a particular situation, would be a constructive exercise than a destructive one. For eg. in matters of integrity, I think of Howard Roark, in being brave I think of Columbus. I know it seems far-fetched, but it actually helps!
