Wow! You really understand what aging in place is all about! The shower chair, pull down shower head, and bedside toilet. All smart ideas. Sorry that your mom had dementia! That must have been tough for you.
No, not so tough but another learning experience. My husband was ill with cancer for 5 years. I had learned a lot in that season of care giving. I was ready to step up when Mom needed me.
Husbands issues were more related to breathing (oxygen), diet, making sure he ate. Physical issues like lymphdema. I had to learn how to do the massage therapy, tapeing and wrapping that was required everyday to keep the swelling and pain down.
I would say I have lost almost all fear of medical things I have learned to manage through caregiving over the years.
