Knowledge of the official Dx was immensely helpful!
Knowing why I am the way that I am helped me develop my own work-arounds and become more socially effective at work and in my home. While people still think of me as eccentric, they no longer reject me outright (well ... most people don't).
Also, being able to understand why my parents and siblings treated me so badly while I was a child helped me to come to terms with a lot of the memories of that time, even though forgiveness is still a long way off.
As for the bullies at school; well, most of them are either dead, in prison, or on Skid Row, and in no position to do me any further harm.
