Hi @delevs 
I hope you're going well, that sounds like you've been having a really hard time but I think it was smart of you to prioritize your mental wellbeing instead of staying for more years of potential workplace abuse and toxicity. It can be difficult to find a job because covid has been tough on business, but around this time of the year I know that a lot of retail stores are hiring Christmas casuals, however, I'm not sure if that window of opportunity has already passed.
To help manage stress, I found that journaling can be helpful, particularly just writing/typing how you have been feeling and getting all that stress out and onto words. I know it's not for everyone though. You can also listen to audiobooks and music, or get try to get into meditation? All these options can be done with your phone as well as with youtube so there's no extra spending.
