This looks much more applicable than the full adhd-pattern. And no, I don't think I'm abused in my childhood. Not in the 'normal' sense of abuse anyway. No violence, but a form of neglect. And most part of the first year in hospital. And I know how I cope with stress without Efexor.

In very short:
