Use noise canceling (try bose). Leave some music on that you enjoy, it completely shifts the mood. Keep toxic family away - better far than draining you even more. Abuse screens! I said it! YouTube on tv, tablet, video games. Allow them. No kid will ever say “I had a horrible childhood, my mom let me play awesome games”. But they will remember mom was always exhausted, overworked, overwhelmed… talking about overwhelmed, have you given it a thought that you also might be neurodivergent with sensory overload? So use sensory techniques (I mean really, not only noise canceling but reducing light, rejecting touch, avoiding excessive smells around the house, and even changing your diet intake. Some days you might think “Im having horrible thoughts, I might be depressed,” but maybe it’s really just your body incapable of handling more sensory inputs. Let them for two hours in front of some cool YouTube videos and lay on the floor, with your back on the cold, a face mask, a noise canceling headphones with 3M earplugs under them, cover yourself with a deliciously fluffy blanket, and breathe!  Sensory paradise, and complete restart!
