scared and undecided re: starting Evenity

I am 67 and my doctors have been urging me to start treatment after my most recent DEXA scan results: R Hip is -2.9 and L. hip is -3.4. I have had two one hour consults with doctors this year regarding making this decision and was about to schedule my first injection, but still can't seem to move forward. After a post viral illness in 2020, I was diagnosed with Chronic Fatigue Syndrome, though I have gotten somewhat better. The last thing I want is a setback, and I have heard that the malaise and fatigue post-injection can be an issue. Also, the COST! I have Medi-care and it seems like the cost will be outrageous. According to Medicare.gov, with any plan my out of pocket drug costs will apparently be $38,000?! Also, I have terrible teeth, despite taking especially good care of them. Have lots of root canals and bridges. I do have a history of a 13 year eating disorder which probably contributed to this osteoporosis! Anyway, I feel quite stuck as to whether to move forward with this or not. Most of me doesn't want to bother, but I do think of the long term risks. They keep calling me to ask me to schedule my injection and I keep avoiding the phone calls.
