I am so sorry to hear of your situation Luckygirl. It is terrible to be put in this situation when your dh needs the care he is getting in the nursing home you chose so carefully for him.
I have no idea about such funding or how you could get help with it. I was just wondering, however, whether there is some way your own pension could be topped up to help with your own living expenses now that you don't have your husband's pension. You have probably explored all avenues but I just mention this in case you are so focused on your husband's care that you haven't thought of pension top up for yourself.
The letter you received is shocking in tone and the cost of care is frightening. My best wishes
