I have been homeless a few times, and moved around quite a bit, but nothing extreme. I do get urges to leave though, when manic I feel trapped and am desperate to explore the world, I think I have some romantic view of living in nature and that's what I'm meant to do.
When depressed and even afterwards, things get so ontop of me and life is so overwhelming it seems to difficult to fix and improve things, and that starting again somewhere else would be easier.
