<human>: Ive been dwelling on an incident for almost two days now that happened on this past Friday, and it's caused me to space out, become so angry I begin shaking, and kept me from sleeping last night as well as tonight. Here's the back story:

 Okay, so I was riding my motorcycle through town, and I stopped in at the bank to grab some cash. Upon leaving,memos asshole looked right at me, and blew the stop sign and came within inches of me, and I almost dropped my Harley. Immediately began yelling, horn blasting. And the guy then slammed on the brakes. I got next to his window and yelled at him, told him he was an asshole and should pay more attention. This eventually turned into a road rage incident on the side of the road as he charged at me afterwards in the car. Long story short, he was some older black guy in his 60-70's, claimed his son was a police sergeant ( or something like that) and started calling me another dumb cracker on a bike and he should have ran me over. Regardless, there was no reasoning with him, and I couldn't tell if he was bluffing or not, so I just took off before he pulled a gun out or something ( I'm in south Florida, it's not so great here). I was so upset that I just flew home, parked the bike and just started yelling, punched through the drywall twice in my living room when I got into the house, and the adrenaline was flowing so much I couldn't stay still for an hour or so.

This isn't the first time I've dwelled on an incident that upset me, but this one was somewhat of a sign that I don't have a release for my anger. It's getting to a point I might have to seek help. The fact that dwell on situations that upset me, replay them in my head over and over again, physically break things and etc, make me feel like I have no control. 

I want to know if anyone here on reddit has some tips and/or tricks to calm down and release without destruction. Some little routines or practices I can instill to help me came down when I'm all amped up and pissed off about something

Can you give me the gist of the text in a nutshell?
<bot>: Had a road rage incident on my motorcycle, been dwelling on it overly, feel that I may need help on releasing/controlling my anger in a healthy manner. Turning to reddit for possible answers before I seek help
