@Bubbles3, as a carer I can tell you how much it hurts, and how helpless it makes you feel, to see something wrong happening and being unable to do anything about it.
Your husband and kids know that it’s wrong for you to not be eating, and it’s hurting them. In your situation your kids are care-kids ..... they are carers too ...... please help them to help you, because everyone has to live with your situation ...... it has to be able to work for everyone .......
I know you love them ...... please work together with them ...... it matters.
