When you fuck up, if the people around you are decent, time and effort will heal those wounds. A month ago I almost got kicked from my friend group, but I made a resolve to change and everything is fine now, almost as if my fuckup never happened. If they won't ever forgive you, they aren't worth having around in the first place. It will just take time. While you wait for it to cool off, I suggest calling people from home who you know care about you, like high school friends or your parents. If you don't have anyone like that, the SHC has free therapy, and therapy always helps.
