Gladys,
I am sorry to hear of your situation. I am not sure that I can help you but I know that it is a noble thing to care for our loved ones. The rewards will never be financial but relational and spiritual. When I was 28 to 30 I ended up being the primary caretaker of my grandmother. I did this till she passed from this life into eternity. There were times with I was greatly frustrated, angry, and depressed, but over all I have found that the situation was a great reward to me as a human being and as a soul.
Most of all you have to remember that our spiritual lives can be our strength when we are falling apart in the world. Being a Christian I believe in the indwelling of the Holy Spirit and know that he taught me so much about love, patience, and hope while I cared from my grandmother. Also, even though we had our problems, I shared with her something and some times that no one else in my family has and these gifts are greater than the trouble of those years.
God Bless,
Marlin
