Should I, or should I not? (A relationship question)

Right now, I do NOT want a relationship. This day and age, I try to avoid relationships like the plague. However, there are a couple of guys that are practically dying to be with me. Creepy guys, to put it bluntly.

I recently told them that I was dating “the man of my dreams” so they would go away. Which is in fact a bald faced lie from hell. I did this because these guys are significantly depressed people and I’m horribly afraid that telling them what I really feel would hurt them badly.

Should I tell them the truth or just let it be? I’m afraid if I bluntly told them “Oh hey, you’re creepy and stuff, get away from me, you’re disgusting.” that I would really hurt their feelings. And I really hate to hurt people’s feelings. It’s just not my thing.

On the other hand, lying is horrible. I hate lying, but I feel that in this case it is the better option.

Am I doing the right thing, or should I just say what I really feel? Both options feel incredibly horrible because I hate being so mean to people.
