If you have anger issues you should seriously consider seeing a therapist (psychiatrist or psychologist). I'm not bashing, I'm saying that you may have deep-rooted issues that you'll never address if you never address them. Think how much better your life could be without the constant anger. Sometimes just talking about it with someone you'll never see again can work wonders for your mindset.
And if you're worried about being a "sissy" or whatever, just don't tell anyone. You and the person you see will be the only ones who know. And if you're worried about the cost, just go once. See what happens. Then you can decide whether it's worth continuing or not.
Make today the first day of the rest of your life.
