Kudos to you for recognizing this as problematic rather than making a bazzillion excuses as to why someone else was to blame and seeing a Doctor right away.
Can't dx anyone, lol, but it sounds like it could be either/and or/both.

I do think it is good that your Doctor took this seriously and started you on meds especially since you have a family history of mental illness.
Hang in there and please keep us posted. I'm so glad things worked out in the end. We needs our jobs.
P.S. have you considered chewing some nicotine gum or wearing a patch at work? I remember when I smoked jonesing for a stogie was enough to make me nearly pyschotic.
