When did you realize Psych nursing was for you?

My mother was diagnosed with schizophrenia when I was 4 years old. I always knew I would end up in a helping profession of some kind, and naturally, psychology was always interesting to me. I was horrified by the way my mother was treated when she was finally institutionalized (this was in the late 70's early 80's when I was a young kid), and I guess I feel like I can somehow make a difference. Who knows, ask me again after I graduate and my first year on the job.....:)
