<human>: Can you provide a brief rundown of the text in within 3 sentences?

long story short, I got rather annoyed with said idividual, which lead to conversation only makin me more so. Being the short-fused, change of heart, moody @AsshatOverlord I am, I thought the best idea was to break of contact; I made as much very clear.

For I while -- that being a couple of days, maybe a bit more -- I actually felt  pretty good, and for a person who spends most of their time feeling down, I saw it as a drastic improvement. However lately I have been regretting my decision very much, and would like to resume my friendship with said person. Only proplem is I don't know how to go about it. I was a less than pleasant person and a shoddy friend, and I feel like anything I might say would just seem either insinceren, or like I'm crawling back begging. This person did hurt me, but not enough to be worth destroying our friendship.

So I guess my question(s) is/are: how would you advice going about reestablishing communication? should I even do it? Do I just need to grow up? or are my concernes justified?
<bot>: messed up a good friendship I a moment of furious anger want to undo my actions. fear how it might come across.
