It's funny you mention this @ CaptainKirk because I was just having this conversation with some of my friends. I land in the middle of my siblings too but for some reason, my parents always expected more from me and held me to stricter rules than my older and younger siblings. I had to play a sport every season during the school year and maintain my grades at an A/B level or I would be grounded, I couldn't see friends or go anywhere on weeknights and on the weekends, I had to be home 9pm sharp. I had many more chores and if my younger sister refused to do hers, I was expected to do hers as well. I had to hold a full time job in the summer, buy my own car and pay for my own car insurance while my parents gave my younger sister a car and paid for her insurance. She didn't have to work full time, play a sport each season or maintain an A/B level of grades. When my younger sister got in trouble, I was punished as well because I was supposed to be watching over her. When I was in college and she was almost a senior in high school, I was working 2 jobs over summer break and was gone most of the day and all night and when I returned home, my father freaked on me because my younger sister told him she wasn't coming home at curfew because I didn't have to. He didn't ask me where I was or what I was doing, he just started screaming at me and grabbing me around the neck because my younger sister, who was only 3 years younger than me, blamed me for her poor behavior. My father didn't hit my younger sister but he had no problem hitting me and calling me terrible names. I don't know what exactly I did to deserve his abuse, but my mother told me it's because I always got in his way so even my mother won't support me to this day. Sometimes, the people you love are toxic to you and though it's easier said than done, you need to realize that it isn't your fault.

It's hard and I am sorry you're going through this. For me, the best thing I did was to focus on what I needed to become an independent adult. I went to college (and lived in the dorms which was heaven even though I'm still paying my college loans because housing was expensive) and I made sure I worked to be able to afford to live away from home after the summer my dad lost his mind on me. I see my family as little as possible (birthdays, holidays, special occasions) and I live my own life. I have a couple good friends and a wonderful husband who are my family and I'm happy to be away from people who don't appreciate me or treat me with respect. Some day, you'll have the opportunity to move away and things will be better for you. Make sure you're as prepared as you can be for that day: focus on what you need to live independently. If you want to be a doctor, go for it! Then, once you don't live with them, you can see if their treatment of you improves. I certainly hope it does. If not, you have your own peaceful home to return to. My favorite quote on this topic is- "The bond that links your true family is not one of blood, but of respect and joy in each other's life." ~Richard Bach~ I hope you find people who bring joy to your life.
