My relationship with my mother has just turned horrible and I don’t know what to do

You can see this as an add on to my previous post but I’m just extremely destroyed now and I need some advice. My mother is the type to speak her mind. I have been tested for ADHD and got diagnosed with moderate depression and anxiety but am still being treated for ADHD. I forget who my mom is all the time.

So here’s the situation. I (22F) told her I don’t know how to use those toasters that she owns with the LED screens, I’m used to just the knob and push it down. And she blew up, saying that she wasted thousands of dollars on my college education. I’m stuck here having just graduated from college, with no money to living somewhere else. I have no one else to talk to about this. I’m crushed, destroyed and just realized with this, our personalities are so different I don’t think there’s any fixing this. I know that she does a lot for me like letting me live in her home. But whenever I make a mistake it’s 1000% my fault and she lets me know, every single mistake, my fault. I just don’t know what to do anymore, I hate living this new lifestyle where every single day I’m wrong.
