Geez, Val, I feel so bad for you, especially since you yourself are still recuperating. I sympathize. Mom and I catered to dad 24/7 when he got worse and as much as I resented it at times, I look back with no guilt at all. Same with mom. Although towards the end she couldn't walk, she wanted me to just move things on a table from "here to there", something she could do. Sometimes I gritted my teeth, but I have no regrets. Now I miss it. Your dad must be feeling ill and very scared, I'm sure he knows something is up. Depression takes on a lot of forms. I hope he gets the medication and care he needs to help him feel better. Call me if you want.
