How do i let go of anger?

I be having an alright day then i think of the years of bullshit and abuse i had to go through and it makes me mald.

I don't want to forgive, i want the people who wronged me to suffer but it's killing me they are living rent free in my head.

Read Roman statesman Seneca's book on anger. Some of the anecdotes there are horrific. If the Romans could control their anger under such provocation so can you.
