Is it normal that i feel no connection towards other humans?

Is it normal that I threat everyone else the same way (in a way of not caring about the person himself but acting like as kindness) no matter if it is a family member or a stranger? I don't really feel emotionally connected towards others and everyone is simply the same for me. It's hard for me to have a simple conversation and to keep in contact with other people because of that.

I don't want to be mean towards you guys with that post. I simply couldn't find another way to say that while the context is completely understandable.
