I Have Low Self Esteem

Self Esteem Problem... I have had a low self esteem for years now and it's only gotten worse since. Even when I was little, I never really liked myself. My problem started when I was only like 9 years old. I don't know where it came from or why I feel that way about myself. I was bullied, but not horribly that I can remember. However, I can't stand myself. There is literally no one I hate more than myself.
