I have bad anger control issues. I want to learn ways to control my anger. So I stop hurting those around me ?

My anger causes me to be mean to people I love most. I want to be a better person but I am failing. I am losing my family because of my stupid anger. My wife hates me now wants nothing to do with me. I just need to either get this under control or I fear the only option to end me hurting others is suicide. Each day that pes I get closer to the second one. So in a act of desperation I am turning to this for a bit of help. So please give real answers I genuinely am at a fork in the road so to speak.
