Osteoporosis treatment

Hey all, I was on Tamoxifen for years after my 1st diagnosis in 2011, in 2015 I had a recurrence, chemo and then went onto Arimidex. A bone density scan showed I had osteoporosis in my lower back and neck :/ mind you I wouldnt have had a clue as its silent. This was courtesy of treatment apparently. Anyway side effects were too much on Arimidex so I was switched last year to Aromasin, theyre pretty much the same oh well. I have been on Prolia injections 6 monthly since 2016 and due for a bone density scan next month. Really hoping for an improvement! I dont do alot of exercise as had no choice but to go back to work full time as there is NO financial help out there and can honestly say it ruined me. I was ER+, the good thing about Prolia is too, apparently it is a super guard on top of Aromasin for prevention, they dont' know why, but it is :) 

So pain and fatigue are the same no matter what I do and working full time, I have no time or energy for anything else.
