The only coping mechanism I have is to breathe and to walk. They help to clear my head. Esp. when I think it's going to explode. you know the feeling your heart and thoughts start racing and you've got so much nervous energy you want to scream? I walk. If it's late at night sometimes I exercise 9either stationary bike or somthing where I move).
You seem him as having all the power b/c he's keeping you from what you want ( in this moment). This is where journaling and writing goals helps. What do you want for your life? How can you get there from here.
There are online classes (even free ones) that can occupy you mind and your time and give you better skills for whatever.
