Devastated

About a year ago, I worked with two little boys, 5 and 6 when I began working with them. They had been in foster care about a year when I began working with them. They also have a younger brother who is now 2 but was only a few days old when he came into care. Both the older boys had behavioral problems. They were physically abused, basic needs abandoned, left with random relatives and friends, lived out of a car, and were shuffled around much of their little life. During the two years I worked with the boys, we fought with the courts to terminate this mother's rights. This mother was 16 when she had the oldest boy and had 2 others after him. She tested postive for meth when she gave birth to the youngest, which resulted in him being taken away. She was placed in jail for driving drunk with the boys and testing positive for marijuana, which brought the other two boys into foster care. During the time I worked with them, she lived in Columbia, Missouri, had sporadic contact with the boys, violated her probation and was sent to prison for 4 months. Finally last year, the courts moved forward with an adoption proceeding for all the boys. The separted the two older boys from their younger brother because they didn't really know him and the youngest had been with the same family since he was born. We went through adoption interviews and interviewed each potential family, trying to see what would be the best fit for the boys. We finally decided on a nice lady who was single, in her mid-forties , had no kids but was a professor at a college around Fulton, MO. The boys were moved there and adjusted fantastically. It was very sad to see them go but we all knew that this was the best placement for them. They would finally have a shot at a good life without being tossed back and forth between foster homes, having mom pop in and out of their lives nad for the first time, have some stability. That was in August of 2005.
Today I learned that they were actually back in town, living with another foster family. Their adoptive mother was diagnosed with cancer and only given a few months left to live. This breaks my heart. The boys are having behavioral problems again(who wouldn't?) and I can't imagine what their little hearts must be feeling. It devestates me to think about all they have gone through and all they will still have to go through. I know God has his plan and it's at times like these that it's most important to remember that.
