Its one thing to
self-conscious (most people are at least some of the time) about what people think of you, everything from what you look like to your abilities at different things. Its another thing to be desperate all the time to convince other people you never get embarrassed or
self conscious and don't care what anybody thinks of you all to keep people around you so that you're never alone, because you hate being alone, and you know damn well you care
more than most what people think of you.
There's nothing unusual about getting
self-conscious, since even if you try to do everything perfect, its not gonna be perfect, and you're gonna do some human shit
and you're not gonna feel proud of what you did. The most
self conscious people in the world are the ones that keep telling you they don't care what anybody thinks of them.
