Some medications that I have been on in the past gave me what my pdoc described as a "blunted" effect. Couldn't tell if I was happy / sad. There was just no expression there at all. Just a blank stare.
I'm sorry that you seem to be having symptoms that might be caused from your meds.
I hope that for you when you see your pdoc you will be able to get some answers to your questions
It's not nice being like this.
