Perhaps get your mom to take you, see the area, meet your girlfriend/her family? That would be my advice. Outside of that, there's really not much you can do. Moms are just... Kind of insane when it comes to protecting their kid. Even when there's not much to protect them from, like in this case. (Really? Meth labs and sex offenders? That's a tad overboard.)
