IME being happy about school reopening is generally seen as a weird reaction, and I don't mean that in a bad or negative way.


It's just that your vacation is over (which upsets most people) and school is hard work. So if people don't realize that campus is your escape, then of course they're going to make incorrect assumptions about obsessions or whatever.


I have no comments on the other stuff you mentioned as I agree with the above that its more about others' assumptions and perspectives, instead of how you actually come across.


I would worry less about all these random people you keep posting about if I were you. It's just causing you unnecessary turmoil, second guessing every action and every word you utter.


Be confident and comfortable with who you are and who people think you are will matter less.
