So, for context- I am 16. I have two little siblings, one 13 and the other 7. The 13 year old is disabled and unable to swallow due to esophagus scarring from an incident when she was little, and she has a G-button. As a result of coddling due to the incident, she has major behavioral issues and is very hard to handle. My 7yr old sister however is very sweet.

Me, my mom and my sisters live in an extended stay hotel. It's very cramped and cluttered, and so it's a small space. Every day of every week is the same. I wake up, go to school on weekdays, come back from school and watch my sisters until 12am most nights. My mom works everyday of the week except Thursday and Friday, and on Saturday and Sunday she has double shifts. So all the days she is working, I'm cooped up in the hotel taking care of my sisters. I've been doing this since I was 11, when my older sister moved out.

Back then, I wasn't in the hotel. We were in a trailer and staying with my sister's dad, who was verbally and emotionally abusive. He was also lazy, and he didn't want to care for 13yr old properly so I was watching the girls everyday while my mom worked, even with an adult in the house. He would drink to the point of blacking out most nights, and I had to deal with the fallout while trying to take care of my siblings until my mom got home. My sister moved out because she had to do the same thing, while dealing with SD's abuse. I used to resent her for leaving me, but now I understand why she left. Anyways, we were in that abusive situation for 15 years before moving into the hotel.

Lately, I've began to resent my mom. I don't have a life outside school and my boyfriend (who of which I visit every Friday after school), and while I know she needs to work and provide, It's just hard. I'm stuck, every single day except Friday, spending every hour in a tiny space meant for two people and not four. Im going to have to do this until I move out. I just really wish I had more freedom, and didn't have to care for my sisters so much. The bitterness is starting to spread to 13yr old as well, due to the way she treats me.

AITA for feeling this way?
