What pill can I take to keep me in a calm mood. I have a problem with my spouse who doesn't stop bitching.?

Sure, I know the best medicine/solution is therapy, so please don't answer with that. I'd like only answers that actually answer the question: What pills can keep a person in a calm mood?

My spouse will criticize and complain. I would ask them to stop, especially after they've repeated their criticism over five times. Their behavior turns into harassment and drives me nuts to sit there and listen to it. If I leave the room, I am followed. If I go under the blankets, the blankets get yanked off me. If i cover my head with my arm, pillows and yoga balls get thrown at me. If we're driving down the highway, I can't get out of the car, I'm stuck. If we're in the house, and I resort to leaving the house, I'm threated with having my posessions damaged and thrown out and other threats. So, with the case of the car(abandoned or unstoppable on the highway), or leaving the house and being threatened, I need to have some ability to stay and put up with this hell. I really don't have the power to shrug it off and not let my lid explode yet.

I just want to know what kind of chill pills there are which would keep me in a mood which would stop me from going ballistic and doing something I regret. It's so painful to go through.
