Just need to vent today

I am really struggling. My 78 dh has VD and is declining physically. He can still do his ADLs but hasn't showered in 6 weeks, even with offers to help. I bought washing cloths, doesn't want them either. He is losing his mobility and needs to use a scooter cart or can use a rollator with a seat for very short distances. He gets weak and out of breath and needs to sit most of the time. We are putting our house on the market next week and there has been so much to do getting this place ready for sale, boxing up 40 yrs worth of stuff, emptying out the rafters of the garage, my husband's wood working shop, 2 detached sheds ...it's been overwhelming. Luckily I'm strong enough to work from dawn to dark everyday but its so hard because dh can't help do anything since he can't stand independently or walk unassisted. When I am cleaning the house or pulling weeds outside He sits down and watches me. I know he can't help it but I'm starting to feel resentment build up. Today we had the carpets cleaned and he had to take his shows and socks off. I saw his toes for the first time in months. Some of his ties nails are 1-2" beyond his toes!!! He had a blood blister i didn't know about on the bottom of his toe. Made a drs appt for Monday to get it addressed. Now if I can only get him to the dr. It will be a fight eventhough I won't tell him until 30 min prior. The handymen here to remove some wooden planters accidentally broke the water main to the house and our water is shut off. I am trying to cope but dh's personality is changing. He is impatient, gets frustrated easily, doesn't comprehend what I say at times and argues with me. He has aganosia and doesn't realize he has changed. I'm trying to stay strong and carryon but days like today really make it tough! Ty for listening, I know all of you understand how hard this is.
