Hello This: I'm sorry I'm not really able to offer anything substantive with regard to this. Perhaps this is all due to the effects having smoked marijuana & then stopped. But I don't really know.

I do believe, however, that depression & anxiety can cause a loss of the ability to feel emotions too, at least over the long term. I'm an older person now & I've been struggling with both for a lifetime. And I certainly have experienced something of this myself. Hopefully other members, here on PC, will have some better insights they can offer.
