I am so sorry for your troubles. It’s so stressful to be the caretaker of a loved ones and then watch them experiencing depression and or sadness. I try not to match his mood. I have reached out to a few friends who have gone through this previously and they seem to understand better than others. I ask them how they coped. I have learned to let go of my perfectionism, for example the laundry doesn’t get separated but it does get done. Sometimes it stays in the dryer for a day or two!! I try to appreciate the small things. I also get up early before my spouse and walk or workout. Finding joy in the small things like the blue sky or the new Spring flowers blooming. Take care and let us know how you are coping.
