All will be well, sis. My aunt has fibro and she's had it pretty much my whole life. She had it before they even knew it existed and was constantly told she was making it up.
Anyway, I don't know what she does for treatment but it's help her a ton and she is doing really well. She retired initially at like 50 years old because of it, but then went back to work. She was an art teacher and went back as a substitute teacher, but she worked steadily up until just last year.

And, she also paints Icons, which is like old style Catholic art. Anyway, it takes a lot of patience and focus which is impossible with pain. So, I know it's 100% treatable and life back to normal.
