How to survive in a stressful home? Where everybody is stressing the hell out of each other?

Spend as little time in it as possible.

Isolate in bedroom, and/or get out of the house for exercise every day.

I have to leave.. even for a few hours

Try and find a little peace somewhere.
One of those times where you probably could be plugged into your phone and block out noise for a while.

Meditate, go out in nature, communicate openly about the problems at hand

Calmly leave and be stress free

Get out for a walk.. music...

Lock yourself in a room

Headphones.

Drink
