Hello Swagglyfishsticks! I obviously don't know your exact situation, but I do know that my OCD can make me doubt everything- including my love for other people, the fact that I care, that I actually feel bad/guilty about something, etc. Since you're posting in an OCD form, I'm guessing (not assuming, since again, I don't know your situation) you may have either been diagnosed with OCD or might believe you have it? If you do have OCD, it's very possible that you do care but your OCD is telling you you don't.

Do you see a therapist? That might help you sort of some of this, and determine whether or not you have OCD. My personal thoughts on the sociopath thing is that, while I obviously don't know for sure nor am I qualified to diagnose anyone, I agree with sideblinded. I am doubtful that sociopaths would care as much as you do about wanting to make sure you care.

I wish you the best, and hope you feel better soon. Maybe you could go do something nice for yourself, like get some icecream! Just a thought.
