I agree too many people get convinced they have ADHD because of something they read on the internet. I went to see a T for depression and was diagnosed with severe ADD/depression. I take medication and work on changing behaviors. It took me 2 years to improve my performance at work. I talked to my supervisor and explained what was going on and I didn't need special accommodations, just time to turn things around. This was difficult for me because the job is complicated and always changing. Now I work on organizing my physical environment, specific and measurable tangibles.
