i am devastated today

Tdy i had brought edison for his routine checkup with his oncology. Edison bone marrow result after his 4th chemo is still unfavourable. Was told his bone marrow still have a lot cancerous cells. Edison will still proceed for his upcoming long surgery on 18th feb to resect his tumor. But after the surgery, he still have to continue his chemo for unconfirmed round - chemo till his bone marrow is cleared so that doc can do harvesting and prepare for his stem cells transplant. Was also told his progress after 5 round of chemo is just average. I am devastated upon hearing it. Many chemo = more toxin into his body = more late side effects. Y my poor little boy need to undergo soo much sufferings. I really dun know how to pray for him. I really wan him to be cancer free. Just 20mins ago, i goggle pastor joseph prince youtube - how to pray powerful prayers -16 june 2013. I feel peace after hearing his sermons. Once again..i know how to pray for my son. Immediately i went to edison bedside and pray " God, i need ur help now. I really dun know what wrong with my son. But i know u love him more than i love him. I'm going to laid my hands and asking u  in Jesus name. HEALED HIM! Now i know..my prayers dun need to be very very long and too complicated and always repeating. A simple prayer is powerful enuff. From this day onwards and every nite before i sleep : I will always laid hands on edison and say this short and simple prayers . Good nite everyone and no worries abt me... i am bk to my positive again!!!
