So sorry to hear about your husband, My Dad had lung cancer and I took him to his treatments. It was very hard and frustrating for my Dad not to be in control of his body or health. Its a tough time to see a family member go through pain and not be able to either fix it or to be there 24 / 7. I crocheted a baby sweater while I took him to his treatments, it kept me calm. I think about that sweater a lot. My heart is with you and your husband. Take care of yourself.
