Living, while suffering

Why does this happen?

Waking up from police and ambulance sirens, with crying and screaming. I wake up running downstairs to the loud noise, seeing that my father had a sudden heart attack. I froze standing there with tears fighting the urge to leave my eyes. All at once my tears create a pool of water under me. Everything is a blur as I start running to my mother, not knowing whats happening. Trying to find my father I then realize everyone has left , just me & my two little siblings, Jeremy (7 years old) and Caroline (5 years old) . With them not knowing what just happened I take them upstairs tell them to take a shower and to get ready as I do their morning breakfast since mom wasn't here. I get their bowls ready, and pour some milk with cereal. Hearing them racing down they come into the kitchen and hop into their seats not knowing how hungry they were until they started eating. As they eat I go to my room take a quick shower and change. I go downstairs on time as the bus arrived for them. I kiss them on the cheek goodbye, and wave to them as the bus started moving. I then get my car keys and speed to the hospital where the other half of my family are there, well only my mother, father who's in the emergency room and my 15 year old sister. I walk into the hospital looking at my watch not caring at the fact that I was late to school, I started to run not knowing the ways then finally saw my sister Jenna. I then saw my mother next to her trying her best not to cry, I told her how he is doing, and she told me to that everything is fine and that I need to go to school, so I won't get another absence. I kissed both my mother and sister goodbye as they wished me good luck to my first day of Junior year. My sister decided to stay with my mother since she doesn't start school until next week. I walk to my car and drive to school, as I looked at my watch I realize that second period has started. I go to the principals office to get a tardy pass and walk into my second period. I realize that half of my class are the bullies, including that Justin kid who used to bully me last year just because I wasn't normal and that I had diabetes. Don't even ask me how he knew I had diabetes, I don't know too. As I walk to my seat I realize that there's only one seat which was next to Justin Bieber. As I sit Justin gives me that badass smirk that he always does when he verbally attacked me.
