You need to talk with a psychologist or psychiatrist. Some people with ADHD have anxiety BECAUSE of the ADHD, others have anxiety as a co-morbid condition but the ADHD makes it worse. In either case, the ADHD meds can (but don't always) lessen anxiety by controlling the ADHD symptoms. It seems we are sometimes anxious about our lack of focus and our impulsive behaviour, (what's up with that, eh? go figure).

Only a personal assessment by a professional will tell you whether or not the stim-meds will help.

Good luck.
