how would god want me to handle this situation?

Three weeks ago (i’m in high school) my ex friend made a messed up joke that ticked me off. i had already stopped talking to her cuz i mentioned something that i didn’t know she wanted private during a conversation while we were in class. This girl is J.

Last week in class she said i lied about the joke she did clearly did make and i had told another girl who approached me and wanted to hang out with me (we were hanging out at school for a few days) that my friend had made that messed up joke. This girl is G.

G and J started hanging out with each other randomly one day and G completely ignored me. So I blocked G and J on social media. G called me a slur while I was minding my own business. Despite me blocking her and not saying anything to her.

When J accused me of making up the messed up joke J did say to me and telling G it, G said I didn’t have any friends and that I was weird, just completely stuck up behavior. I cried because I felt betrayed. I also felt angry. It’s not fair because this girl is completely well to do with friends and people like her meanwhile she is mean and they were mean to me. I’m a closed off person and these people usually approach me wanting friendship and I’m nice enough to open myself up and this is what I get in return. How would god and jesus want me to handle these emotions?
