Am I wrong

So every time I come home from school I try to sleep and rest up after waking up early in the Morning and walking 25-40 minutes in the the cold snow to get to school but I never get the chance to because my mom is always going somewhere and makes me babysit and it really annoys me because my brother who doesn’t go to school and doesn’t work sleeps all day does nothing and doesn’t get asked to babysit he’s 19 and I’m 16 my mom always ends up coming back home late and I end up staying up late to finish pacts of homework am I wrong for being annoyed at her I just wanna sleep for a little bit after school and my brother to babysit at least once

I’m also 26 weeks pregnant so I barely get sleep at night and get really bad stomach gas at night that makes it hard for me to sleep

And I feel like my brother has zero responsibilities while I have like hundred and I know me being pregnant changes nothing but I also feel like my mom is still mad at me for being pregnant so is making me babysit when I don’t have to
