Found out the real reason my mom was so mad at me last night.
She's been doing what I do. She assumed I was mad at her because she keeps falling asleep in front of the TV. She thought I was yelling at her, which I would absolutely never do. I've been trying to help her enjoy her wind down time in the evening without falling asleep early, because that leads to her waking up way early. So now I don't know what to do. I'm not angry with her, I'm angry with her body for betraying her. And I'm burning out on trying to find ways to help her.
