(((((hugs))))) That is not an easy situation you have on your hands, and I really feel for you. You're in a tough position. Your mom is most certainly very toxic.

Can you walk away from her when she gets like this and tell her something along the lines of, "I will not tolerate this from you. When you can speak with me with respect and caring and truly hear what I am saying or explaining, then I will talk to you, but not right now." Then leave the room. She may yell and not like it, but that is setting a healthy boundary to protect yourself from her outrageous responses.

Do you have your own living space where you can gain some peace? Do you have any coffee shops nearby where you could bring your computer to apply and look for jobs and/or conduct your part-time remote jobs? Or perhaps a local library? Do you have headphones so you can listen to soothing music to help you chill out, relax and get away from her?

I live with my parents who sometimes drive me crazy, I work remotely from home too, so that's what I do when I'm going insane.

It will just be a matter of time before you're able to earn & save enough, get another job and eventually move out... in the meantime, you've got to protect your sanity and mental health in any way that you can.

Not sure if this helps you any, but I sympathasize... ((((More hugs))))
