I had some thoughts for this person. I really felt bad for them. Ideas were floating around in my mind last night and I wanted a little more information before I wrote my thoughts. It might take me some time to find the response to this question but I will be looking forward to try to give some suggestions. Who ever you are with the question about their loved one not receiving adequate care and not knowing what to do, you are in my prayers.
