My dd6 is a mess. Raging tantrums and telling me and her sister she wishes we were all dead and to go away. I feel like if I am the safe and sane one then they ought to be able to be ok w me and dd6 is worrying me gravely. She is and for many years has been totally unable to calm herself down. Couldn't self soothe as a baby (xAH shook her and screamed at her a lot as a baby bc she was so fussy) and she is angry at me and her sister all the time especially in the last few weeks. I just feel like everything is crumbling more than ever and I don't trust myself that I am strong enough to hold it together.
