I am the sickly child

 Since the age of 4, I have had to take differnt kinds of medicine like allergy med, nose spray, nasal stray, pain killers, asprin, and some other meds to relive pain that comes into my life physically and mentally. I have been told that I am cold-hearted, ruthless, cruel, scary, and mean by many people including some relatives, but I have to because if I express to much emotion I start to get dizzy, have mood swings and breakout in violent streaks. My sisters have never gotten sick so I think that I have a weak ammune system out of all my sisters.
  I don't ever wish this pain or sadness I have on anyone else because if I were to have never grown up at a young age of 10, I couldn't take care of my successful big sister and popular little sister.My big sister is 16, my little sister is 13 and I just turned 15.
 Before when I was 7 or 8 my mom put me in Ballet lessons, at first I hated it but later on loved it but one day my mom told me to stop all-together, my mom said it was for my own good but my dad said that my health got worse because I would get sick everyday but still practice which only deteriorated my health little by little but we couldn't go to the hospital back then because we hardly had money then not even enough to get a phone, or computer.
 Me and my sisters were brought up by hardships and difficulties but we were disciplined to work hard and start cleaning around the house by the age of 5. Even so my little sis got the royal treatment and hardly cleans, my big sis got into a advanced high school like an early college with college courses and is to busy to clean so I am taking over 2 of my sisters chores and at the end of the day they take the credit for what I do.
 At school my sisters tell me to pretend I don't know them because it would embarrass them to have a sister like me. Though them saying that hurt deep inside my heart I cant disappoint them and drag them down. All I can do is Write stories, read fast, listen to music and clean our house. Due to the stress I collaped at school about twice, all the worry's, and labor took a toll on my body.
 I got accepted into the school my big sister got into because my mother wanted to. I think this school might be too much because my big sis who doesnt do her chore can hardly handle the school assignments. And the only reason I got accepted is because I am always in the shadow of my sister, so everyone expects me to just as good as my sister. It really painful to actually hear your teachers say that since Donna is smart that is expected of me. Its like I am not even myself, I am my sisters sister to everyone.
