I think I know what you mean. I can't say I completely understand because everyone is their own own person and has their own thought processes but I have experienced a fair amount of what you describe. Basically I've always done what you have done. Question it. Am I the only one? Does everyone go through this? Why do I even care about these mistakes? I think it's just the human condition. Social anxiety or whatever. We live our lives in a world with other people so it's not out of the ordinary to care what everyone thinks of you. It can be a freakin pain in the ass but I think over time everyone learns to overcome it (except for maybe a few with brain abnormalities who cannot cope with them). I dunno what else to say, but thanks to your post it has made me that much more positive that we all go through relatively the same drama.
Also, highschool doesn't matter, it's your life when you're in it and that's all there really is but once you graduate it just becomes a stage in your life.
