Bullying? I don’t know how to cope.

I found out a couple days ago, my friends online were talking behind my back. they called me annoying multiple times, and they repeatedly kept saying how they didn’t like me along with another person. And it’s really just been eating at me these couple days. I left the group once I found out. Confronted all of them. A couple responded a couple didn’t. Then after that blocked all of them. I don’t know what else to do. To feel better. My heart aches whenever I think about it. I feel terrible and I can’t believe they would do that and say things about me. I’ve already been struggling enough and this was just the cherry ontop to make me feel worse. And I hate it so much. I don’t know what to do. I deleted the app today and didn’t wanna log in.
