The best thing you can do is learn how to breath. I mean really breath. Take long deep breaths. 4,7,8 technique is great for relaxing you.
Exhale all the air out your mouth, close your mouth, breath in 4 seconds through your nose, hold for 7. Exhale hard through your mouth. Repeat and hold for 8. Do this as many times until you calm down.
This works because the breathing helps relax you naturally and it gives you time to use your mind to think logically and not on emotion. If you do that you'll find that most things aren't that big of a deal.
I suggest you have a hard physical outlet that same day too to burn the physical energy that comes from anger too.
