I think I saw more depression symptoms listed but it's tough to say. When you are depressed you concentration, focus, and general cognitive functioning will declined. However if you can't concnetrate due to ADD that can cause depression because of all the frustration you have. You may just need to find another job if your not happy at all. Defintely see a psychiatrist first and print out that list of symptoms so that he can make the best possible diagnosis. Then he will either put you on an antidepressant or an ADHD stimulant medication, and it will be trial and error until you find the right med.
