Starting over

Help we need a home.  After a 30 year marriage, my husband was caught having an affair in our home and our daughter was the one that caught him.  Two days later he left to move in with his Mistress, leaving the house with a morgtage that has not been paid in over a year.  We have a daughter who is emotionally distraught and has difficulty dealing with the situation and is under medical care.  We don't know when we will be thrown out of our home or where we will go.  My future exhusband has said he will help me anyway he can to save the home but he has not even made an effort.  I am partially disabled because of a back injury and have only been able to find a part time job to support us.  It is very hard for me to be the one asking for help since i am one that is always there for everyone else.  I have lost a lot of faith in life itself and don't know where to turn.  Please help me fund a home for my daughter and myself.   God bless!
