I can't even begin to know how you feel because i'm 0% empathic :/ I used to have a high empathy level but after almost going full blown insane a few times i got rid of my emotions...

I have something similar and that's having gruesome thoughts, urges, and cravings to eat people, drink blood, and kill things... I'd never act upon these things but they do make me hungry thinking ...

It's called loneliness but for some reason i haven't experienced this feeling for a while now... even though i'm alone almost all the time.
