Why cant I be normal ?

Why do I have to be the one that has overbearing everyday struggles? 
I look all around me and I see normal families. I see happiness and laughter. I see people creating lives and memories. I see people living normal lives. 
I look inside my house and I see an abnormal family. I see hatred and destruction. I see people being abused. I see pills and needles for people who are not in full health. I see a broken family. A family only kept together by the mere fact that 3 of the members are only minors, and have no other choice. But in the road ahead, i see not a family, just 5 people who are only connected by blood, and are trying to forget the past that they had together because it is just too painful to remember.
