I had to deal with this with both my parents, they had a decent amount of savings but it was not effectively invested. It took several years before my Dad was willing to change their investments. They decided to move to senior living in 2017, by 2019 they were in assisted living - thankfully they did have long-term (separate) LTC insurances that paid for most of their LTC costs. Dad passed in 2020 (due to medical complications) and Mom moved to a higher level of care later that year. In 2022 she was moved to the mental care (dementia/alzheimers) wing of the facility, and the LTC policy was covering 90% of that cost. She passed in August of 2023, which was a blessing as she hadn't been able to speak for over 6 months and was not responsive. Thankfully, money was not an issue because there savings was able to cover the insurance shortfall, but we were looking at how long that could be maintained as her LTC policy would have reached full payout by October.
Talking with specialist is a great option, there could be things you can do that someone dealing with families making these transitions are not aware of . Also I would advise looking into hospice care, there is long-term hospice care that may be covered by Medicare. We only found this out a few weeks before my Mom passed, and only because a new medical director at her facility was pro-active in getting this started. In all honesty, no one in my family thought about it, and she could have had those services for probably the last 8-12 months.
Good luck with this journey, it is a difficult road - stay in touch with family and close friends who are aware of what is going on. This is not a path that you need to travel alone.
And ignore the assholes who throw out hateful comments - that is a bit much, even for the assholes on this site.
