DAE feel like the description for a sociopath sounds about right for you?

I have a loving family, a good job and a wonderful girlfriend. But since I found out My grandad died when I was 13 I've been kind of numb to everything and although I may act like things have upset me or bother me that's only for the social aspect like I would expect other people to be upset by it so I'll act a certain way or would react to it like my friend would so I try and emulate that. I should also say that feeling this way is not dangerous for people around me for those who don't understand, I would never hurt anyone, I do have feelings for many things but it just doesn't affect me like most people... being a 'sociopath' sounds harmful but I promise it's more harmful for us than people close to us.
