I'm in a similar boat, and do not qualify either. It sucks, but that's life.
With that said, I would really hate to not be able to take my car anywhere I need to go, because a good day can turn bad quickly. In fact, it is among the many reasons I am glad to have moved to a rural area.
The parking spots aren't just for people with wheelchairs. My grandmother got one when she had to use a walker.
You deserve it!
