Help My Sister Renee Keep Her Home

My name is Robin.  I have a very small but amazing family, the nucleus of which is my two sisters, Ronda and Renee, and myself.   Renee has been married to Ray for almost 20 years.  They have an 18 year old son, Liam,  and a daughter, Maddy.   Renee has had many health issues recently, to the point that she isn't sure how much longer she can physically work.  Because of this Ray, always putting his family first, began working 2 jobs.  They had many financial struggles, but had a plan to have themselves on their feet financially.   Through it all, they remained the epitome of the hard-working family; devoted to one another regardless of life's ups and downs. 
On Thanksgiving morning Liam found his dad laying unresponsive on the living room floor.   After a long day of tests and waiting, tests and more waiting, the prognosis was devastating.  Ray is currently in the Neurological Intensive Care Unit.   Anyone who has ever had something tragic happen unexpectedly knows that there is nothing anyone can do to alleviate the emotional pain of sudden tragedy.  Nothing can be done to ease the devastation or the grief in those first days after devastating news.  But, the last thing a family struggling with emotional pain needs is to suddenly face the possibility of losing their family home.   Renee does not have the financial resources or means to pay her mortgage and other household expenses alone.   She, Ray, Liam and Maddy have a difficult road ahead of them and it would be an amazing gift if they were able to pay the balance of the mortgage.  Ray and Renee worked hard for their home, please help them keep it, as well as paying other household bills like car payments, groceries, etc.
Thank you.
