Forced to serve as free childcare
Recently due to legal issues that my parents are facing, they have moved themselves and me (F16) to the Cayman Islands to live with my half sister.
This sounds fine but they have taken me out of school and I can't go to school in Cayman as we are on tourist visas. My half sister, who I'm living with is an evangelical christian and has two children twin 3 year old girls. Everything with her is about God, her husband (that is a whole other thing but she is super obsessed with him in a way which an adult woman should not be) or her children.
Yet despite this, I am made to do 90% of the childcare. Because I don't do school or anything else during the day, she has decided to force me into looking after her children whenever she wants a break which is basically all of the time as she uses her pregnancy as an EXCUSE.
I don't get a break ever and none of this is my fault, unlike her who willingly chose to get pregnant. I can't even properly reason with her as she is autistic and can't really be reasoned with on a lot of issues and doesn't understand how to hold a conversation properly. Even my mother who is a huge advocate on abortion gave up arguing with her on it as she cannot be convinced to change her mind on certain things.
The kids aren't that bad and are quite sweet most of the time but I just want to not be serving as an unpaid parent while their actual mother has a breakdown because her husband won't answer her calls while he is at work.
Sorry for ranting I just am fustrated at my current situation and wonder if there is anyone who has had a similar experience or can offer advice on how I can bal privacy and doing childcare
