Am I giving off weird energy or something?

I’m for the most part pretty quiet. Ngl I’m the butt if the joke most times. However I don’t understand. I feel like people choose me to pick on or just not like me. I hang with the group of people from high school. It’s not the best dynamic for me personally but I don’t do anything to anyone. But one of the girls in particular chose to not invite me to her bday trip and invited everyone else but me. I didn’t address it cause I probably wasn’t going anyway because of money but it’s the principle. So I don't know. Then my roommate who I thought was cool with me decided to flat out ignore me in the lunch room. I don’t have any friends on my own campus but I thought me and her were cool but apparently not. And she has been stealing from me which I have to address. There are a couple of other girls who dislike me for some odd reason and I’m just confused. I don’t even talk to anyone. I don’t say anything why am I receiving so much hate. I don’t understand what’s wrong with me.
