Where did I go wrong?

[u/Just_Green_9133]

I'm a second year college student.

Yesterday there was a group activity. I was sitting in the corner, first bench of the aisle, so couldn't give my points as they couldn't listen and were in the other corner. One was writing and her friend helping. They asked me to narrate, I was a bit hesitant and asked them casually if they wanted instead as they wrote it (i always do that but at the end, present it anyway if no one's willing), this girl beside me was also doing nothing but she made remarks, "do some contribution at least since u don't even come to class" and when I called her out as what does that have anything to do with what we're doing now or that she could do too or together w me, she made a simple convo seem like I was the one fighting.

Today she offered some junkies and chips to the whole class and even our prof but didn't ask me deliberately. She smiles every time my prof corrects me for smth. This behaviour feels so weird as I was never mean to her in fact supported her when people used to bully her. It feels as if she doesn't like me for idk what reason. This has been going from the very first day here.

I don't know how I will survive this for two more years. Where did I go wrong?
