Is there anyone in your masters program that you can ask for help until you get back on your feet. I've been in a similar situation in the past, and never asked my colleagues for help because I didn't feel we were close enough. After the fact I found out that many of them were appalled that I hadn't asked them for help, and would have gladly done it. This was in the southern U.S. though, and I'm not very familiar with German culture; The culture difference may or may not make this as feasible.
