Picking fights and regretting them later

Does anyone else have this problem? I picked a nasty fight over the weekend that I regretted soon after, and I apologized (and they accepted), but I definitely damaged the relationship and I don't know if I will ever be able to fully repair it. This person means a lot to me and I think I mean (or meant) something to them. I feel like a real dumb a#####e. I could probably cross post this to addiction since ofc I was drunk and on caffeine when I did this dumb s##t. I think I'm going to pour all that stuff down the sink and go dry for a little while. :|
