How to make friends?

This sounds dumb but...are there groups or something on fb that's for moms to meet up and hopefully become friends? I dont have anyone to hangout with or go out with, with or without my daughter and I'd like to be able to find someone who I get along with and can have a great friendship with. Any help would be appreciated! I dont want to just say"someone be my friend" lol. Or if you use to go to school with someone but never really talked...but you both have kids and same age..do you just add them on fb and then message them and slowly start tryin to build a friendship? Lol this is so sad. Thanks ladies!
