Because:
You haven't been able to
Control the Anger by Yourself.
You don't want to lose Your family.
You don't want to lose Your job.
You don't want to go to jail.
You're embarrassed by the Anger.
You've hurt people You love.
You're tired of Anger controlling YOU!
Or, any other reason that will make Your life better!
Maybe you
should ask yourself what it will cost if you don't?
