Am I An Empath? Emotional Sponge?

Hey guys,

I've always been able to sense other people's emotions, just tell what they feel. It's always been pretty mild, until 3 or 4 months ago. I feel like an emotional sponge, I'm 13, and at school, I have a friend who's bipolar/suicidal, and I always "take in" her emotions, not just her, I mean...I'm overwhelmed with different emotions, about her, it's almost like I was helping her, she's always depending on me, because she says she feels normal when she talks to me. My school is pretty big, and I'm always stressed in large crowds.

Also, people I've just met usually find it easy to talk to me about their problems. Like, the other day, I met a friend, and the week after that I talk with him, and he says he feels bad, he explained to me that his step-mom kept screaming at him and he was fed up about it. I mean, this is something very personal to him and I was very touched that he shared that with me.

Also, I've always been able to sense different entities, I've actually blacked out once with a frightening demon-goat face. (I know this belongs in the other website, but it has something to do with Clairvoyance, which is a psychic ability.)

You see, at my home, I'm aware of an entity here. It's always following me, wherever I go, and whenever I wear my religious necklace (St. Benedict medal on a chain), I get nauseous, like, edge of vomiting-type nauseous.

Thanks for reading, I'm in need of answers, it's really stressing me out.

Have a nice day!
