Hi,
This is a hard thing for you to go through. I know because my husband had lung cancer, not dementia but he needed my help all the time just like your husband needs you. I didn't want to leave my husband alone either and only went for necessities such as groceries etc. Many things can be delivered. I didn't want any outside help simply because you don't know who you can trust these days.

Your husband is probably feeling scared and realizes something is different about him and can't actually understand what it is. My husband felt that way also. It's hard to not get depressed as you said but your husband needs you more than ever. I don't mean to sound harsh but he won't be there forever. I know because my husband died in 2024. I am so glad I spent the time I did with him. Now I have all the time in the world to do what I think I need to do; shopping, take a walk etc. and I just wish I had him back. I miss him terribly but I know he's up in Heaven and out of pain. We'll be together again in God's time.

Give all your problems up to God and let him handle things for you and he will. God helped me and my husband a lot and God is still helping me get through a very sad and lonely time.

If you have any questions or just need to talk, I am here. I have a lot of time these days. I'll say a prayer for you and your husband. It will be OK. God will see to that.
I wish you the best.
