I don't know that I'm an over achiever, but I've always been ambitious and have achieved most of my goals, and have a job I'm proud of. I've also always been terribly hard on myself. I can sit in one spot for hours and mentally beat myself up. When I screw up, I assume people are thinking the worst, and I find it hard to forgive myself. I think that's led to me feeling isolated and lonely, which led to me becoming addicted.
