Ana’s last breath...Help for family

My brother’s wife Ana has been battling breast cancer for a few years now. After many hospital visits and chemo therapy, she was doing ok and seemed to be on the right track. 
However, this past week she has had sudden liver failure. There is nothing the doctor’s can do to save her. She lays in a hospital bed, living the last moments of her life. Doctors says she has at least a couple hours, a couple days, or at most, a week left to live. It’s devastating. She will be leaving her husband Matt (my brother) and their only little boy Martin behind. Her life is a miracle that is meeting its end. Please help Matt & Martin with all the expenses they must face. Unfortunately, finances is always a factor in tragic times of our lives. 
They live in Spain, Ana’s home origin. This make traveling expenses even greater for their family in the USA, where Matt is from. They need help with the high cost of airefare to fly to and from the states. 
His mother (who lives in Pennsylvania USA) is eager to get to him in Spain. She needs to be there for her grieving son and grandson. Medical bills, traveling, and many other expenses are going to flood through. No one wants to worry about money in these times. Please help however you can with these various expenses. However big or small. Thank you.
