Is this normal?

Is it normal to NEVER miss or want to see someone? I'm not talking just about relationships or family, but friends as well. Anyone at all, actually. I never miss anyway, I literally don't know how it feels to miss someone or to have that "omg I wanna see them so bad" feeling. Also, it doesn't matter how much I get attached and how much I like someone in terms of relationships, I can never say that I actually love them, my feelings are strong and it does hurt a lot after it ends but I feel like they're never that deep if that makes sense? I would want to talk to a therapist about this because I don't really think it's normal at all.. 
Maybe the thing that I have self harmed in the past and thiught about suicide made me like this as well, I do enjoy my time alone a lot and I prefer being alone than going out with my friends or something like that.
