Jefe, stop digging for intel. It's not productive. As a musician you have a fertile imagination - good for music but bad for being a LBS. It keeps you up at night - not good. Learn some thought stopping techniques and whenever a thought of your W with OM1 or OM2 (reminds me of Dr Suess Thing1 & Thing2) enters your head, recognize it and picture a stop sign and stop that thought - think about something else. It takes practice but I've gotten a lot better at it. It's easier if you don't go looking for intel. That just focuses your mind on the wrong subject matter.
Focus on areas of your life that are not in turmoil.
As for your grandma, she needs a falls assessment done as well as a good analysis of her home to minimize the risk of falls. There's lots of good stuff on the internet about that - Morse Falls Scale for one. Falls with seniors is serious business. Focus on that.
