My mom and step-dad want to move?

They want to move this summer, before I start high school. I don't want to leave. I'd be moving far away from where I currently. live. I don't want to lose my friends. I have really bad anxiety, so I'm terrified of having to meet new people. I could always move in with my father, but I'm scared if I bring up living with my dad, my mom wouldn't want to leave anymore. I don't want to hold her back. What do I do?
