Is it normal to not really show empathy?
I have a small friend group and we're nearing the end of our high school careers. I've lived a good life in a good home with good parents. However, because of a couple video I recently shared in Facebook, both of which involved someone being hit by a train, my friends who I have come to love since freshman year suddenly started calling me a sociopath because I didn't have empathy for the people who were hit. Now, I didn't share the videos for kicks. I shared them to try to show people what happens when you get hit by a train and for them to understand that no one wants to see that happen to someone. My goal was to get people to think twice before trying to beat the train.
At the request of these friends after a long night's argument of if I was mentally stable or not, I saw my schools guidance counselor who is also a licensed psychologist. She said I was fine but recently I've been starting to question my mental state more and more because I'm confused on whether or not what I'm showing is empathy. I don't have symptoms of a sociopath other than lack of empathy, or so it seems. Should I be seeking help or are my friends nuts?
