I want to call out

For context. My supervisor is just awful. She berates people, sets me specifically up for failure and hates when people stick up for themselves against her.

Short story : She's going off about the amount of copies and I defend myself explaining i did word for word what she asked of me. I go toe to toe with her. Nothing excessively rude on my part. This is perhaps the 8th back and forth we have with each other in my 3 years. Other times I just just let her bully me. This is the 1st to reach a new level of anger. I bite my tongue so much and Tuesday I just snapped. I asked her if she took pleasure in being rude to me and she blew up accused me of calling her "cruel" I realized this is childish but this woman is truly wicked. I've NEVER had this kind of supervisor before. Ive contacted HR and I have emails of my complaints and nothing ever gets done. Its gotten to the point where I hope I get hit by a car on my way to work to avoid her.

Anyways I dont want to go back to work tomorrow....Is there a safe (for me) way to call out? Other than the "im sick". I just need another day away from her, my nervousystem cannot take another confrontation like that.

TLDR: I hate my supervisor, she hates me. We argued and I dont want to come into work tomorrow because I'm honestly still shaken by the experience and I need a good excuse.
