Help for Elderly Widow

My Mother Bella Danziger is 92 years old and has been a widow for 33 years.  She is currently suffering from the onset of Dementia and requires many different medications to treat her High Blood Pressure, Irregular Heartbeat, Depression, and various other issues related to her age.  She currently lives alone in a Senior Living Center in Chicago, IL.   She has no surviving brothers or sisters.  Her rent is $1760 per month and her Social Security and her small pension are not enough to meet her monthly expenses.  My wife and I cannot assist her financially due to the care of our 31 year old mentally handicapped son which requires full time care.   Any money raised will be used to cover her monthly expenses which fall short each month.   I would be very grateful for any donation size, no matter how small.  Thank you in advance!!
