Blog about diabetes

My name is Sara and I am new here. My mother is a 53 year old brittle
diabetic. She is currently in a rehab for two broken legs (one due to
a low blood sugar fall.) My second problem is that she is BiPolar
(manic depressive) and Schizophrenic (hearing voices). She will not
eat propery and refuses to check her sugars. She takes her insulin
whether she needs it or not.
I am trying to find a way to help keep her on her diet. She will not
usually eat unless she is taken out to a restuarant for dinner. And
will not eat leftovers. Is there some sort of pre-made meal that I can
get for her? Or since she likes meals that are from restuarants do you
suggest a meals on wheels kind of thing?
I know it is all up to her but if I provide everything then maybe she
will help herself.
