@vrwcaj I am so sorry, and I hope you find your circle of friends soon. What are they saying behind your back?
This will sound incredibly insensitive, but I’m just going to throw out some extreme cases. These might require a neutral person to tell you the truth.
Do you look like you haven’t showered in a week?
Do your clothes look not-so-clean?
Do you have body odor?
Do you have bad breath?
Do you have a bitchy resting face?
Do you not notice when people say hi to you?
Do you affirm others during class? (e.g. “Cool shoes.” “That’s a really good point you made during the discussion, and I think…”)
Good luck!
