Sounds like your husband was a brave man. A man to look up to. In many ways our partners or spouses who live on are left holding the pieces of a former life that is now fragmented. Coping with loss is a loss in itself. Of ourselves, our well-being. Motivations not there. But change is necessary to overcome this. New interests or morning routine. A pet maybe. A new perspective to refocus your thoughts like reading. My mind is fuzzy too. I tend to read illustrated comical easy to understand stories. Draw or write. We have 4 cats so I always have a companion close by. I have a precancerous illness which only makes my stress level go through the roof. Not knowing but still living with possibility of having cancer is always on my mind.
