Yes, just a joke, and NOT intended at your expense. As for the other I see two general possibilities: People are effing with your mind with a stupid practical joke. Don't play their game and don't give the the satisfaction. Don't get angry and instead take the high road. I was once immature enough to enjoy that type of humor, but later realized what a colossal dumb ass I was. or If nobody is actually leading you on, then you are imagining it. For your own sake, please get help. It could be something as simple as an easily corrected chemical imbalance. It will not hurt to get looked at and could greatly improve your quality of life.
