I get anxious during lunch?

Ok so over spring break they finished up our new cafertiera which is smaller than our old one seeing as how we have a 3 and a half year construction project going on. And well I sat with a bunch of outcasts and now I sit with a bunch of man whores and the chick who gave my number to my current number and they're all loud and annoying and is the biggest whore on the face of the planet. And well I'm afraid she's gonnna either take my phone from me or ask me if I'm still dating this sex addict. Truth is I am and he's changed and he blames ur sister for making him the sex addict. I can't even have my phone on vibrate anymore during lunch and also I'm afraid that she or her sisters texing him. What should I do?
