When you break your leg you're not slightly injured and then get worse over time. I was using your example and showing how it was inaccurate. Your new example about losing your job etc is completely different.

That said, also in that case the climb up is not sudden like frame 3 suggests. Rehabilitation is a long grueling process, not something that happens overnight. You can provide whatever example you like, but progress never takes on the form of frame 3. Only in extremely, extremely specific examples it could happen, and those are absolutely an exception rather than the norm.
