Dude, your life is like my life. I'm currently obsessed with getting into med school but last night I decided I should put all my effort into law and public administration (wtf?) but prior to that it was veterinary, law school, wealth management, vet tech, international relations, languages blah blah blah. I would rarely lose focus in class but meeting deadlines has just gotten worse and worse in grad school. I had to take a medical leave of absence because I never went to class and always had to beg my teachers to accept a once again late paper.

Anyway, I feel ya. And my grad program sent me to a neuropsychologist and he diagnosed me with ADD. Because of that evaluation, I am now a registered student with a disability, if that helps you at all. It's sort of helped me but there is still a stigma attached to the label which is a double edged sword. On the one hand, you can get more time on tests, take more breaks, etc. and turn in papers late and your professors are required by law to make these accomodations. But on the other hand, I've found that many professors do so grudgingly.

on the brightside, I can tell you that after Igot hte ADD diagnosis and regsiterd as a student with a disability I went from not even being able to complete exams to scoring 100% just because I had some extra time to calm down.
