Input: So here's the story, about a year ago, I reconnected and rekindled friendships with a group of friends who I have previously been assholes to. A few years ago, I was a prick towards them and they made fun of me during the period for being a prick. I admit I did deserve it as a was a major asshole to them back then. When I rekindled the friendships with them a year ago, I made it a priority to change my behavior and to show them that I wasn't the same prick anymore. I even made fun of myself on numerous occasions of my previous behavior to show them that I acknowledged it was run. However, they have been making fun of my previous behavior recently despite it being a few years ago. I did tell them that I know I was an asshole but its in the past there's no point repeating the same jokes over and over again. This wasn't very successful as they would tell me that although it was in the past, it should not be forgotten. I've tried distancing myself from them recently but I've gotten quite lonely. They're my only group of friends and I really do think of them as nice people. However, its just this ribbing that bothers me. So am I just an oversensitive asshole? 

getting mad at my friends for making fun of me
