Sorry you are dealing with so much.
I am on Tamoxifen after bad side effects from Exemestane and Letrozle. I also had Osteoporosis before treatment. Prolix stabilized me.
Everyone has different issues with all this .
I am 77 and asked what studies are done on older people who take inhibitors, nothing was out yet.
My quality of life is important. I can tolerate Tamoxifen but wonder how much I helps at my age,
Good luck
