I have a anger problem, i get angry at such small things, i'm 17 years old, any suggestions?

Feeling angry: One simple tip- count to ten before acting on the urge to impulsively harm someone physically or emotionally. Reduce anger by deep breathing. Breath in deeply & slowly through the nostrils. Hold air in lungs for a 5 count before slowly exhaling through an open mouth. Repeat until you cool your jets. Focus on your breathing not what is making you angry. Cognitive behavioral therapy is excellent for.
