I feel burdened as the only daughter and a middle child

I'm a middle child and the only daughter in my family. Since I was little I was used to wear my brother's hand down including clothes, toys and books. Growing up, I feel like I don't want to get married in the future since I saw how my family interact and works. In my opinion, my family is quite disoriented, no one tries to understand each other, no one tries to listen to other's story or opinion, and they (especially my parents) focus on their ego too much. I also don't really have a good childhood with constant beating when I wasn't able to do well in my studies. But this is another story in other time.

Now, I'm 20 and rn is in university but because we're having pandemic, I went back home and have online classes. My parents think that since we're staying at home it could be more or less similar with school's break. I'm an introvert so the idea of me going outside and hanging out with friends aren't my cup of tea. I actually enjoyed this stay at home thing and only went out if I need to do something. My mom and dad are both working so I and my siblings mostly stay at home by ourselves.

The thing that I always got mad is, the double standard I got just because I'm a girl. I've been tasked to do everything in the house including cleaning the dishes, cooking the rice, cleaning the house, laundries. I also need to pick up food order if my mom doesn't really want to cook too much that day. Need to massage my mom if she feels under the weather. I also need to help my parents to sort the papers from their work, also need to help my little brother's with his studies.

Other than that I also need to do my assignments, need to take on my freelance work, group work and quizzes. My mom also doesn't do any grocery shopping since 1 year ago ever since the pandemic started, so I need to be the one to do it or else we got nothing to cook with. The worst thing is, I buy the grocery with my own freelance money.

I know some people may feel like I'm whining or this is just because of period hormone doing something nuts, but I just feel tired of it. Honestly, living in other town and away from my family could be easier. Both of my brothers didn't help with anything and just laze around playing games all day. I need to wake up at 9 am, do the laundries. Back to do my assignments, and classes. After that I need to do the remaining chores. Need to help my little brother with his studies, then do my own studies. After that I work on my freelance work, and ended up sleeping at 4 am in the morning. Days goes on and on.

My dad even commented that I shouldn't be too skinny, I should be waking up earlier to get the sunlight, I should eat more, etc. Not helping me with my works at all..
