How can I stop thinking of other people?

It seems like it's the only thing I think about, even when no one is present. Right now is not the time to do so because I need to get my life together. I have low worth and social anxiety so it's hard for me to go out and meet new people (doesn't help that I'm in a new place). Don't tell me to join groups because I got my family right here and that's all that matters. I'm leaving later anyway. Anyway, I get sort of paranoid at Gyms because people do in fact stare at me and I always wonder if they are doing so or not. Only about the same sex though. Men fascinate me with their confidence and their bodies. So many men have come up to me shyly and ask awkwardly if they wanna talk, but I never do because I work alone. I want to stop thinking about men most of all, but it just won't stop! I love them too much. I think I'm going crazy. It feels like (not saying it is) every guy likes me, but idk how to tell them that my biggest enemy is myself right now. I'm not focusing on anything else until this matter resolves! No matter how much that I love you . . . .
