Anyone in the Montreal area could suggest a name for a good doctor to potentially diagnose and treat ADHD? This has been going on all my life and I am extremely fed up with it, I cannot list one single thing I ever finished 'properly' in my life (35+) and this include important academic and work tasks.. I don't want to 'have' anything , or justify my possible laziness/ineptitude, but I want to have professional making the call. Thanks...
