Hello, I am sorry you are going through this. I hope you will find the best treatment options for you, that you will be able to do as well as many others have.

I was diagnosed with stage 4 breast cancer 3 years ago, mine is HR+ HER2-. It had already spread well into my bones but hasn't spread into any organs. They started me on treatment pretty quickly after my diagnosis in the hospital.
My treatment is CDK4 6 inhibitor Abemaciclib (Verzenio), aromatase inhibitor Exemestane (Aromasin), GnRH agonist Leuprolide Acetate (Lupron Depot), bisphosphonate Zoledronic Acid (Zometa) along with pain meds for both regular and nerve pain and calcium with vitamin d. I also take a few supplements to try and help with some of my side effects as well. Melatonin (for sleeping), Tart Cherry (for deeper sleep), Magnesium Glycinate (for anxiety).

I don't feel very well at all since on my treatments, I have a lot of side effects but many people don't have those. Unfortunately, I have to continue my treatments indefinitely, in order to control the spread of the cancer.
