Will my python ever recover?

[Bogertophis]

As previously suggested, she needs things with traction and to climb on to improve her body condition- as it is, she's got nothing. You did say you're making something but she's been without for 11 years, I assume, so what do you expect?

As hides go, those are awfully tall & not a bit "cozy" or safe-feeling as most snakes seem to enjoy- though I can't speak for this species on that.

She needs some real environmental "enrichment"- some things to work her muscles on. When I had a large boa, I used indoor-outdoor carpet as substrate- it's easily washed, & offers great traction. And on top of her hide, I used a carpet mat with rubberized non-slip backing so she could comfortably climb on & off for basking- again, snakes need traction to work their muscles against- smooth surfaces don't do a thing.

Have you ever seen someone put a snake on a glass top table? The snake can hardly move as it's so slick. Snakes push off surfaces somewhat like ice skaters do with their blade edges, only they're using their muscles & belly scutes. (& yes, I used to ice skate) As it is, her home looks more like an office cubicle...not anything a snake would be comfortable in. I half-expect to see a typewriter & a telephone in there. There's a lot of air space- but snakes don't fly- they need things to hold onto, things to climb on & explore.

Snakes can feel very stressed from such an open (& very illuminated) environment, or from repeated vet visits, without ever showing visible or measurable signs- but they just may not do well. Stress impacts their immune system. Snakes are stoic creatures- it's up to us to understand & provide for their needs if you expect them to have good health & longevity, as opposed to just existing.
