You are worrying what people think of you? But actually most people have some much going on in their own lives that they are not concerned about anything you are doing unless it directly affects them in a negative way.
I don't mind so much online what people think of me they come and go. I don't like making a fool of myself in front of other people. I don't have to think about anything the minute I get into a crowd I get nervous and shy and awkward.
