Hi Geraldine,
Welcome to OCF. We all understand the fear you are experiencing now. We have all felt scared and it is totally normal. I urge you to stay active on the forums here and ask as many questions as you have. There are a lot of people who are caregivers and they can help you. I always tell people I think it's easier to be the patient. Hang in there and know you and your husband are not alone...we are all here for you.
