Look, I have no Idea, what it is like to be traumatized by school, I generally left at lunch because I was up to no good, and made it back most days for practice.
I can tell you that i graduated #157 of 172 kids in my class, and as a result missed out on alot of $ in football scholarships at some BIG football schools.
I did however graduate and went on to finish college twice, and am currently a middle school teacher (go figure). I teach with a lady whom I graduated high school with (she was like #5 of 172). We make the same money. I also have several friends, who either got a GED or dropped out, and they are all across the board on what they are doing now, from prison, to making $100k+ a year working in a trade. Unless you have some very specific skill you can market, or unless you intend to further your eduaction in some way (trade school, apprenticeship, whatever) my opinion, is get some help from some one whether that is your school counselor, or your parents, somebody. until you have a plan laid out keep plugging along. Do you need to graduate? Certainly not. You do however, need a plan before you decide to walk away.
