Do you have a smartphone or device that can download apps? I have been reading about 'snugsafe', it is supposedly a free app you can have on your phone and you check in on it everyday and if you don't check in, it will send a text to whoever you have put as your emergency contact.
I have an anxious daughter who checks on me every few days, plus I am still working and probably my employer would check on me after a few days, but I plan to retire in three months and so maybe I will get the app.
One of the reviews of snugsafe was a person who said that they set the snugsafe reminder time to be when they needed to remember to take their medicine, so they were getting two convenient uses of the app that way.
