First off, there's no neurological condition called "depression". It's a psychiatric disorder, specifically, an affective disorder. It's not accurate to speak of "neurological depression". A neurologist would send you to a psychiatrist if your only symptom were depression. The OP has that plus some other psychiatric ("mental") dx, so none of this is neurological.
Secondly, I am not suggesting he eschew meds in favor of CT, but that, since he's already got the appointments set up, CT is what he can look into in the meantime
, which is the strategy he asked for.
I have a diagnosis of "Major Depression", myself, and have variously tried several anti-depressants, none of which made a dent in it. Cognitive Therapy worked wonders. The San Diego County Mental Health system uses it in all their group therapy sessions (which, of course, are done in conjunction with meds).
No, Cognitive Therapy was developed for people with severe, lifelong dysfunctional depression.
