I've had bad attention span, low motivation and been disorganized since i was a child, but i've never been hyper.is it possible that i have adhd?

That is possible.: Recommend psychological/ psychiatric evaluation for attention deficit disorder . You don't have to have hyperactivity and impulsivity.

Yes.: You could have ADHD without the "H" and have all these symptoms. You might also have an underlying mood disorder. Children with emerging bi-polar illness often first present with one or more of the Attention Deficit symptoms, plus mood issues. Go to a child psychologist for more info if you are younger, or someone trained in this area if you are an adult.
