Bumping heads

There's so much going on at home. My dad has been in the hospital for 3 days so far fighting for his life. I've been so stressed and moody, so many emotions to handle. My husbands father is in jail because he's being accused of pedophilia. So he's upset and I'm upset and we're just constantly going at it. He takes out his anger on me and vise versa. What advice can you guys give me to kinda mellow the tension in my home. It's only been a few days and I feel like punching him! 😒😔
