Missy, I am so sorry to hear what you are going through. It is a good thing that he can still walk around and he is in the comfort of his own home. My father spent his last 2 weeks in the hospital, couldnt move or eat or say anything much.
Time is so valuable now - spend as much of it as you can with your husband. Give him every meal that he wants. Keep turning on soothing music and keeping his mood lightened. Cheer him on and tell him it's all going to be okay and the journey ahead will be a beautiful one!

Big hugs. And also take care of yourself. Sometimes a caregiver focuses so much on the patient that we end up being unwell physically and emotionally.
Praying for you and your husband and hoping God will give you the strength you require to face the upcoming days.
