How to destress after work so I dont destroy my time off as well?

Guys I hate my job so much. I am an activity aide at a chain retirement home which sounds like a great job but most of the managers treat me like actual trash and expect me to do the work of like 3+ full time individuals and frequently expect me to do unpaid overtime and work im not licensed or regulated for and its such a hot mess. Everyone there is extremely negligent and I feel like Im the only person with my brain turned on at any time while also having the least amount of power im losing my mind. Every day is a fresh fresh hell. Recently PSWs have started harassing ane bullying me for not being fun enough when most of my job is just managing crisis after crisis caused by my insane and evil floor manager (my direct manager is the only person who I respect god bless her but she doesnt work on my floor). A brief example is me (part time min wage activity aid btw) personally somehow being responsible for saving a womans life because ???? Nobody else bothered to show up?? None of the care team???? But then immediately after that a PSW throws shade at me for not running an activity when I am literally in the middle of preventing someone from being left to die on the floor because nobody bothered to come help her for an extended period of time EVERY DAY IS LIKE THIS!

Aside from filing all the nescessary reports to the ministry of long term care, probably the police tbh, and getting a new job, in the meantime how do I relax when I get home? I get home so angry and upset that I just storm around and rave and have bad dreams every night about work and sulk and its such bad vibes. I need to do something to calm down so I dont ruin all my time off and my relationships as Im sure everyone is sick of hearing about it.
