Hey Jason
Like Rob said, it happens with the best of us. Had a similar incident last week Monday, experienced a hectic two days, and finally for no reason snapped it at some poor guy at the general dealer who only wanted to help me out with a few stuff carrying around out of the shop. I flipped my lid towards him. Felt pretty horrible but strangely stubborn at that moment and the rest of the day. Now on Tuesday I usually have my church group in the evenings and interestingly the topic of discussion that evening were about examples in the Bible where someone(in this case Jesus was used as an example on the evening before he got crucified) had to get out of their comfort zone. I immediately felt God spoke to me, as He said to me I should get out of my comfort zone as well. You know what I did? As tough as it was for me as I had to swallow my pride, I went to that same general dealer the next day, and the guy I were rude to, were there again. I decided to buy him a coffee and speak to him for about 20 minutes, and apologizing for my bad behaviour two days before. The conversation eventually went very well, and I felt God blessed me during the rest of my week for doing that.
