So tired

I am 72f with stage4 ckd. All I want to do is go to bed. I want to stay there, but I feel guilty. I’m married to a wonderful man. We are both retired , and dote over our 5 year old Bichon. I can honestly say my only reason to want to leave my bed are to take her to the park or seeing my daughters who live far away . I somehow do whatever I can to see them. I travel to nyc to see one of them or to San Diego to see the other one. Anything else like food shopping errands, housecleaning , I feel like I’m moving mountains. Does anyone else on this feed feel this way? You’d stay in bed forever , if you could . I love being under the covers so much !
