Need to vent

So im 13 years old and my sisters (twins) are 9 and my brother turned 3 months yesterday. So me and my sisters are doing online school due to the pandemic. My parents asked me a couple weeks before my brother was born if I wanted to watch him from 6 to noon now I said yes because my sisters were going to be home and some days my dad was goinv to be home. But when the baby was born everyone was attached to him and now my sisters are like drifting from him which I get i mean there 9. But my dad on the other hand in the entire 3 months the babys been here has never MADE a bottle, fed the baby, changed a diaper, gave him a bath, wont hold him for more than 5 minutes, he wont even get up and give him his pacifier when the baby is in his swing right beside him either me or my mom always have to come downstairs and get it for him. My mom always says that my dad was like that with me and my sisters. It still bothers me. But I try to ignore it because thats between my parents but at the same time the things my dad is doing I always end up having to do. And im only 13 i feel like my teen years are being taken away. So tonight my mom had to go into work at 10 pm instead of 6 am so my dads home but i knew I was stuck watching the baby from 10 pm until noon tommorow. My mom didnt have to go in that early she just wanted to so she could help with something at work. I begged her not to and she said I was being dramatic. I cried and said I just need a break. I have been suffering with anxiety and depression alot lately. And I just need atleat one day off but she told me im being dramatic. And now im sitting here feeding the baby at 10:45 pm. Ik im probably being really dramatic but what do I do. I feel as if im only good enough to watch my siblings. Also I forgot to add everytime I try to say something to my parents they always try to get me to be quiet and they just try to ignore me and ignore the situation. Im just tired physically and mentally.
