I sense a lot of anxiety on what if situation and some where you need to also put check points about what you are able to do and how much you are able to accept.... going to a new family is not easy it's almost like when you shift to different climate your body adjust according to the new weather but takes a bit of time... like wise you are going to new family  so you first need to accept the things the way they are and then if you like with what you have it ok else modify things slowly and with patience to see the desired result.
