Hi
@cannygirl
My sincerest sympathies for your long wait.

Even coming up on 5 years post BTHR, I can certainly recall the last 6 months before surgery.... the never-ending pain from bone-on-bone osteoarthritis, the sleeplessness, the depression....

I was still working...but just minimum walking, sitting, and standing caused pain and I can't imagine trying leg Iifts or other exercises.
I steamed my hips and back when home with a heating pad for a scintilla of comfort.
At best, I could control my weight with diet due to my lack of exercise... tried to eat healthier to keep my immune system cranking.
I also think if you concentrate on exercises for your arms and upper body that this will prove super helpful during recovery.
Having both hips done at once, my upper body strength enabled me to do more early days without assistance.
Once you get that new hip, you can work on regaining muscle tone and strength.
Staying positive is hard at this time, but I tried to get out and find distractions in order to stay sane.
Hope your date comes soon.
