I am a 18 year old au pair and I arrived to my host family around 4 weeks ago. We did talk through emails and skype before I came, and they seemed to be really nice, but I am compeletly ignored ever since I arrived. They never asked me any questions, I am only talked to when it is about the kids. I told the mother quite a few times that her sun ia cursing and hits me and her 2 year old sister with different objects, her reaction was the following: I know, but it is getting bettef.
I am feeling really unhappy, I have troubles with sleeping and eating, when I see the kids, I start shaking and I cry almost every day. I know that this situation us also my fault, becouse the might not like my personality or becouse they thought my German would be better or I would be different, I don't know.
How could I bring this up to them?
