Hi and welcome. Dysthymia is another term for persistent depression but your doctor will have to/will have made that diagnosis. It’s fairly common now to have a multi pronged treatment program of medication, support and talking therapies. As the study that the report you heard today shows, there are many ADs available. What it doesn’t say (I don’t think) is that different people react to different ADs.

ADs do work and there are several types you haven’t tried. I’d suggest you talk to your doctor, perhaps book a double appointment so you have time to really talk things through
