My first thought is that there's too many "sometimes". I see the point your trying to make, and that you need to sound fairly redundant to let the reader know this is a person down on their luck and kinda tired of being there. But maybe cut the "sometimes" down a bit?
You've got me wondering though. Is this about a person actually living in a junkyard? What an interesting idea. And of course that makes me wonder how they came to that point, which in turn makes me wonder what you're story is about.
