I griefed a minecraft server
Why would you have done that to the server?
Because of a very abusive server owner who gave me a ban without a warning.
It is unfortunate that you had to deal with a bad server owner. It is not a good idea to escalate bad online interactions, though. Maybe you should look for a new place to hang out and play minecraft online instead.
Minecraft helps me take my mind off things so I need to play.
Well, you can't play if you harass other users and get banned from playing. You need to follow the rules if you want to play.
