Screaming is good. I've done that - drove to a seculded spot and screamed and cried for an hour. Beat the steering wheel, threw snowballs at trees, came totally and completely unglued. Gosh, it felt great!
Once, when I was still living with him, I went to the garage and broke every pint glass and wineglass in a box marked "Salvation Army". Every single one - crash on the concrete floor! Of course, I had a big mess after but it felt good to just VENT it all out in a safe place where no one could get hurt (unless they were hiding behind the tree where I was throwing snowballs!)
Hang in there, stay strong!
