Sitting here, trying to stay cool

I've just been thinking over some things about myself. My entire life I've spent looking after someone. First it was my mother, who was blind. Then my nephew came along and I had to watch him while my friends went out and enjoyed their teen years. Now it's my aunt. Granted, i managed to fit in some good times. I had some friends who were close but it was still not fun sometimes.

I feel selfish for wanting more then being someone's caretaker. I hate that I want to go and get a job so I can make my own way in the world. But it's normal, right?
