mistreated

Hey guys! I'm sorry for the length of this, I just felt that it was necessary to let you all know everything that has been going on. I'm hoping to get some good advice on here becasue I am truly stuck right now..
So I'll go ahead and give you all some background info on this new family..

I am relatively new to nannying and although this is my first nannying job I feel very mistreated and not appreciated. I am trying to leave this position but the family refuses to let me! Please help!
