My mom gets mad at me when I’m sick.

So I’m 20 and visiting my mom to support her in something that has been really difficult for her. Well I happened to get the flu and apparently she’d mad and called my dad to complain because I’m staying in the living room which means she can’t go in the living room. This isn’t the first time though. As a kid she’d get mad about it too. I once cried when sick and went to her for comfort, so I knocked on her door and she yelled at me to go lay down and closed the door and left me to cry. Then she also didn’t care when I had vomited on myself and didn’t even let me change. As a kid, she always found ways to get mad at me. I felt like she was always mad at me. Our relationship is better, but sometimes I wonder if she’s just gotten better at hiding all this anger.
