Could my anxiety post op be a reaction to the type of anesthetic used?

            Plastic surgeons frequently see depression and anxiety after many types of procedures, but, at 5 weeks, you should be feeling better.  I would agree with others to see a psychiatrist who will be more familiar with symptoms and diagnoses and will be more familiar with SSRIs, mood stabilizers, and anxiolytics.

I would encourage you to see a psychopharmacologist.  This is a psychiatrist with fellowship expertise in psychoactive drugs.  This honestly is a much better resource than your GP who may know one or two drugs.  Generally a certain percentage of patients have a mild clinical depression after surgery but it can also be an anxiety disorder or a even some form of psychosis.  Whatever the basis for your feelings, even if the episode is short lived, it is unpleasant.  Get real help for this.  This will help you feel better faster.
