The after effects of getting bullied as a teen (body image/weight gain or loss etc)?

I used to get angry and upset at the people who picked on me while in school. Sorry if this sounds wierd but I now thank them instead because they taught me to be careful of, and understand, the nature of people. It's a dog eat dog world. I'm still alive and that's what matters. Lesson learned. Later on I found out, from past teachers, that many of the bullies I knew eventually ended up ruining their own life. Either via jail, drug overdose, etc.
