Personally, what really helped with my anger issues is to learn how to be mindful.
It's not that I put time aside to meditate or anything. I just try to be aware of the negative shit I am thinking about and then tell myself to be aware of something new. So I just breathe, and think, "I am breathing."
That's it. That'd cut the negative bullshit.
Not everyone has the Time for Meditation . You said what helps you with your anger issues is to be aware of the negativity and try to calm down by breathing. This is the first step! Try to see always the positive aspect at first and Smile because it made you stronger!
