I have a neurological condition, Cerebellar Ataxi, where it’s or uncommon to experience emotional blunting. It is where you know intellectually that you would feel sadness, happiness, etc in a certain circumstance but you do not feel any emotion

I have occipital neuralgia and it is difficult to live with. I never know what to expect. I have brain fog and it’s very frustrating

I have Cerebellar Ataxia, a degenerative nervous system disease. I term what I am experiencing as ‘emotional blunting’. I no longer feel joy, sadness, etc. There is even an article on the connection written by a renowned neurology ataxia specialist. I’ve had antidepressants, psychology testing and a psychologist talk therapy at my own request with no impact whatsoever.
