I am sorry you are going through all this. Have you tried posting on Connect's Osteoporosis and Bone Health section?

I have increased my muscle mass over the last two years (and hopefully my bone density, haven't be re-tested) thru strength training. I don't know if this is an option for you. If you do end up taking a drug, be sure you research the side effects so you can make an informed decision. For instance, with Prolia if you get that injection you cannot just stop taking that drug, it may cause fractures. You need to relay to another drug. But some doctors don't know that. I am not saying the drugs are bad for you, just that you need to fully understand their benefits v. risks and how to manage the administration of the drug. I got dinged big time with not understanding omeprazole, which I was told by my doctor had no side effects and I should take for the rest of my life. Live and learn!

Good luck!
