Don't worry about sounding shallow or petty; you are going through a very difficult issue and it's natural to be frustrated, especially when you see someone else get better care. I have the same feelings a lot when reading people's posts here; I can't imagine finding half of the resources I have read about here, and I know as long as I am controlled by work comp nothing like them will get approved. So yeah, I get jealous too; don't sweat it. Just focus on your recovery.
