That's a lot to cope with!
My mom lives with me, too. She has needed several medical procedures, including two hip replacements. She has developed a life-threatening infection in the last one. The infection has been going on for 9 months now.
it is being kept under control right now with massive amounts of daily antibiotics. It has been one crisis after another, late nights in the ER and late night emergency surgery, etc. It's exhausting! All of this just to say: you are not alone.
Keep on venting/posting.
We are here to support you.
I hope your mom will be okay!
Love and prayers for you and for yours,
