How long does it take to get over being angry with yourself?

I was in a gaming community. A few mishaps did happen between me and a few of the other members of that community. I was kicked out for those mishaps. I do think we are both at fault because they didn't communicate those mishaps to me that well. I talked with another online friend about it and he pointed out things I did wrong. I did think about it and now I'm angry with myself because I could of handled the situation differently. Some of the things I did wasn't communicated by my group that well.
