Please send positive thoughts

In addition to my sister having severe diabetic neuropathy in her feet now, they told her that her bloodwork showed very high white blood cell count. She recently went in to the ICU for ketoacidosis, a condition that can be fatal where blood sugar is so high that acid levels rise in the blood. She asked her PCP today about the high white blood cells, and she said they are very high; so much so that it 'could' be indicative of Leukemia. That she didn't want to scare her, but to get the blood work redone this week. It has just been one awful thing after another, and now to even consider that my sister 'may' have something as serious as cancer, I can't wrap my head around it. She is my very best friend and she doesn't deserve any of this. Please send positive wishes if you can... I am so on edge and anxious.😢
