and sorry for the typos I type fast ...
I am sorry you are having a hard time , losing your home must have been very traumatic for you, I have found that when you hit the bottom the only way to go is Up, think positively all will be well.Perhasp your daughter has heard a lot of drama and this has upset her, she has losts toys and things she valued. She is reacting to what has happened , give her plenty of posuitive talk, tell her tough times dont last but tough people do, focus on every positive aspect including how you are all healthy, eating and have somewhere to sleep .It may be a good idea if she is having problems with the step family to lessen the visits for the moment, maybe you guys in your new place go out,as much as you can to leseen the smallness of you all crammed in , parks, play board games, focus on family ..reading, have family reading nights , wher all take a turn to read out loud ..Good luck you will come through this and it will make you stronger .....
