Advice on creepy guys

So I need some advice. Whenever I go ANYWHERE there is always at least one creepy guy who either follows me or just STARES. I don’t even like going to the gym now because there are always these creepy ass guys who can’t keep their eyes off me. What do you ladies do? I’m so fed up with it. It’s like I have a bubble around me that attracts these guys. I’m in college and a classmate followed me to my car twice last week and told me about how he wanted to kill himself and stuff. I don’t even know his name. Am I supposed to confront them? I don’t want to make it worse but I’m scared everywhere I go.
