Whenever someone gets really, really hurt -- be it emotionally or physically -- I /literally/ feel a sudden shock through my heart that goes down my spine and all the way down to the rest of my body. I don't want to say it like that, but it's kind of a warm, fuzzy feeling that leaves me wanting to feel it again and again.

It only happens when someone is REALLY, REALLY hurt. It's not like I laugh when people fall down or anything. I don't feel AMUSEMENT from people getting hurt, it's just this feeling that is kind of hard to explain... But it feels good and I like when it happens and it happens quite a lot.

What is it? Am I a sadist or something? Or is it just empathy? I don't imagine that empathy for such a horrible thing would feel good. Is this normal -- I've never heard anyone talk about it and searched things but could not find anything.

I'm a fourteen year old boy, not diagnosed with anything really, just curious.
