My spouse is mostly inactive and watches TV 24 hours a day. With BvFTD, he is not able to recognize his mental decline. He has become childlike and passive most of the time but can lose it completely in an anger fugue in public over something minor. We rarely go out. I just can't seem to find a good way to be at home all the time. I've stopped going for walks, and don't enjoy doing things on my own.
If he can get out is there an Adult Day Program that he can get involved in. this would give you a break a few days a week, it would give him a break from you and being in the house 24/7.
If your husband is a Veteran the VA may provide a few hours of caregiving, they may also fund the Day Program.
It is also possible that your husband would qualify for Hospice. If he does you would have a nurse that would come each week to check on him, a CNA that would come 2 to 3 days a week to give him a bath or shower and order supplies. All medications and supplies would be delivered to you. You would get the equipment that you need to safely care for him as well. And with Hospice you can request a Volunteer that would sit with him while you get out and run errands or just take a break and reconnect with friends.
And a great benefit of Hospice...it will cover almost a week of Respite care so you can get away for an extended time and really get a break.
BUT....just because your husbands health is declining doesn't mean that you have to let yours decline as well.
Other than talking to your doctor about getting on an antidepressant, you can schedule meeting a friend or friends for lunch or supper weekly, go to church and meet other women who like to do what you do, and get out and at least walk around your neighborhood to get some fresh air and exercise.
And if you need to hire some outside help to allow you to do that, please do.
You have to realize that your life will go on when your husband is no longer here, so it's best now to start forming what that will look like.
My late husband didn't like to leave the house either for many many years, and I being a people person needed that interaction with others, so I made sure that I was going to church, meeting up with friends for lunch of supper, taking day trips with friends and living and enjoying my life best I could. And my husband thankfully didn't mind me being gone for a little while.
Now of course as he got worse my outings were more like running to the grocery store or just sitting outside on my back patio, but I still made sure that I was taking time just for me.
You matter too in this equation. Please don't forget that.
