husband;s complications

My husband had his first chemo, a double dose, it knocked him for a loop, and it cause him to get a bacterial infection of the urine, then the blood, he is in serious condition, but we hope at this time, he can finish him chemo. The chemo will only give him some more time, and maybe inprove his symptoms, but if it causes the infection to come back, we do not know if he can tolerate this. I am going day by day, do not know what else to do. I guess I will vent on this page. I am not ready to let go, but he is showing signs that he is ready to let go. He is tired, he hurts, he can't walk, but we have a small window of time, maybe we can improve things for awhile. I am running out of optimism.
