People have already explained perfectly what an empath is. I'm gonna tell you you should look into protecting yourself. You don't want to take the energy from other people and put it on yourself. Someone who's in a bad mood could put you in a bad mood. Look into crystals I have a few that I keep on my person wherever I go it's like a forcefield it protects you. You can still be an empath just don't take the baggage home with you.
