@emotionalnumb I assume the medication that caused the emotional blunting is Invega?
I experienced emotional blunting aka flat affect from Risperidone injections. Another byproduct of my injections was anhedonia, which is specifically the inability to feel pleasure. Unfortunately in the case of Invega, probably the only way to get your emotions back is to taper off Invega and wait. I'm sure you've read at least some of the Invega thread but I'd recommend reading it closer and perhaps even visiting the previous Invega threads. An anti-depressant may or may not help but it's worth at least trying.
My psychiatrist is the one who told me about emotional blunting, so yours should know what it means.
