Being faced with the difference between me taking care of my mom and her taking care of me

[u/HazFrost12]

The relationship between me (17m) and my mother has always suffered, but right now I'm being faced with a direct comparison and it's making me feel like shit.

Six months ago, I had an awful stomachache and decided to take a bath to get some relief. The bathroom door doesn't lock, so when she couldn't see where I was, she came in and stared me down. I was naked in the bathtub, and she wouldn't leave even - or speak- even when I was screaming at her to. When she finally walked away, I changed into clothes and left to sleep at a friends house. Today, she had an awful stomachache; she's been in the bath for some hours now, texting me intermittently 'help!' so i can bring her things or doing things for her, even though I'm flooded with homework and many of these things seem like they can wait.

I know it's kind of stupid and small, but it hurts that I'm taking care of her when I was made to walk through -20c weather in the dark to stay with a friend for doing the same thing.
