It keeps getting worse…

I need help understanding and dealing with my relationship with my mom. Lately, she has been becoming increasingly mean and critical toward me. It feels like even small things I do—or things I don’t immediately know how to do—turn into a major argument, and she often blames me.
For example, she expected me to know her location even though I had no way of knowing where she was. She has a newer iPhone but doesn’t always know how to use its features, and instead of asking me for help, she sometimes gets angry and calls me stupid or uses insulting words toward me in profanity…. I don’t know what to say anymore…. I just don’t even feel like this is a meaningful conversation anymore with my mom everything that goes WRONG is always my fault like today her tire went flat so I let her use my car even tho i missed my sisters volleyball game…
