Why do i still want to live?

I have had a terrible life, when i was nine, i was bullied and had to move school. When i was eleven, my parents always fought and i was physically abused. A few months after i turned thirteen, i became pregnant through rape. When i was fourteen i gave birth to my now four year old son. ever since then when i walk down the street people look, stare whisper "look at that slut!' and things like that. But no-one knowss that i was raped at thirteen, no-one know that my son, my beautiful, son with an ugly past has a jailed father, no-one knows and nobody cares. i want to know, if it's normal to hav gone through all this pain and trauma and still want to live. Is it normal to have gone through so much?
