My husband has Alzheimer’s disease with mixed dementia two years ago now but I too have struggled with coping with the symptoms. They are different but similar to your husband’s. I decided to do the understanding dementia course with the Wicking Dementia Centre online which is free and I have put the link below. If you don’t feel that it’s any good for you now they do offer it frequently later on. Otherwise ask on the forums for help with symptoms because that got me through. Now I just suffer with the constant decline but my doctor and dietician are supportive and I have got help with personal care. He has had 2 respite stays and I have booked a third end of February. We are self funding so it does depend on your own circumstances.
However to give you an idea, today the carer bounced in, he met and greeted her, said he was fine! She said when’s he going to respite, he said what’s that, I made a facial signal to her to avoid it. I said you need a little holiday and he said we are going together aren’t we and I just said um. I wouldn’t have dreamed of saying no you are going on your own and I am having a break from caring for you. He can’t accept that he is ill and that I need any relief. He won’t remember and I won’t tell him until he goes and help him with it. Later on she apologised for being so open and she will learn from that. Being economical with the truth, fudging the answer and keeping him calm are absolutely necessary for me, it makes no difference to him. I had to learn what I call ‘dementia speak’, it’s lonely because you lose the person but they have gone anyway. The links to it are on the website and I am sure one of the moderators will post it if you can’t find it. I can look it up and post it otherwise. My main stress now is his refusal to eat more than meagre amounts but he will drink Fortisip twice a day. It’s awful and he has burned up all his fat, muscles are thin and his strength is ebbing and there is nothing I can do except press on, and on.
