My ex-wife became ill in July 2015, passed away in February 2016. I have receipts for $7700.00 direct expenses caring for her. Is any of that deductible

She moved back into my house in July 2015, died in Feb 2016.  I filed 2015 taxes for her. She had only 2700 income in 2016. Is any of the 7700.00 dollars deductible?
