Exercise intolerance and air hunger - will this ever be fixed?

For the past 2-3 months of my taper, I have become exercise intolerant.  Whenever i do try and exercise, i can't sleep, and the next day my anxiety is through the roof and i get air hunger because of the anxiety and it really takes a toll on me.  Does anyone have any input on how to get better with this?  Of all the symptoms and side effects I've experienced, exercise intolerance and air hunger are by far the worst for me.

Any advise on how to get back into the swing of things would be greatly appreciated.

I wish I knew, I am going through something similar and haven't fully withdrawn yet.

It has kinda been with me all along since I started benzos and only gotten worse. Mine is accompanied with pain in my right side. I find if I don;t take my next dose in time I tend to get it very badly. Is this the first time you have gotten it?
