It sounds like you have some symptoms of hypochondria, like you are obsessed with possibly of having ADHD. Now, you could genuinely have it also. Your therapist could be wrong, and its at least worth a shot of having her screen you for it. If she disagrees, then possibly go to an ADHD specialist in the area and have them thoroughly screen you for it. The problem with this diagnosis is it can mimic other symptoms such as anxiety disorder, or some forms of depression. For instance, the inability to sit still in ADHD is caused by psychomotor restlessness, whereas in an anxiety disorder it is a fight/flight response. Makes sense? What makes that even tougher is that ADHD patients tend to have a lot of anxiety already. So for you to get a proper diagnosis takes quite a few tests and visits I would think. That's my opinion.
