Celexa is an antidepressant and sometimes used for anxiety, I believe. I’ve never heard of it treating ADHD symptoms.
Common treatments for ADHD are: stimulant medication, non-stimulant medication, and some meds used off-label (Wellbutrin, tricyclics, etc…).
There are alternative treatments too, like diet, exercise, meditation, brain training, and supplements.
There are some clinics around that do free or sliding scale appointments and evaluations. That could be an option.
