How to get through the next month?

So my current apartment lease just ended and I am staying with a friend while we wait for an apartment to open up in late November. He has a 1 bedroom, so I am crashing in the living room. He works retail and has varying late hours, so sometimes he gets in late or works during the day and stays up late. He is also not that tidy and doesn't clean up his messes. I work 9-5 and like to get to bed around 10-11 and I haven't be able to keep my schedule. Also, the lack of privacy is not cool. I could possibly stay at my moms house, but I feel bad staying there for a month and then leaving. Plus, I would be putting my nephew out of his room. How do I get through this?
