If it helps in anyway I don't care about them at all, but care a lot about you.
FB sucks indeed, all the gossip and hurt that goes on there gives me a heartache.
There are many, many people that you can trust for real. I hope you allow yourself to welcome them in your life. I hurt a great deal when I know someone is badmouthing me especially someone I trusted, but it saves time in the long run! perhaps there are new people that you need to know and they need to know and learn from you, and God didn't want you to keep losing time. It is something many here have in common...we start changing little things within... and many people get out of our lives... and new ones, healthier ones take their place... its all good and much better... you are just in the "in between"... cheers!
