I was at a party the other night and I was out with a group of friends and everyone was cool, we were smoking and drinking. Then later on, this guy who I was smoking with grabbed my backpack from the floor, and then said it was his. I got in his face and told him that it was mine and still he said it was his. My friends were behind me and where telling him to give it back and finally he did, but to me he was clearly a threat,now I don’t know if I can walk by myself without having to worry if this guy wants to harm me. (maybe he followed me back from the party) As a result of I’ve been out of breath sort of scared, I don’t know if I’m just being paranoid, but are these symptoms of some kind of depression or probably death threats that I’m receiving.
