Because:
You haven't
been able to Control Your 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 your 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?
