I've been in your shoes. Well not literally and only some of them. I backpacked for a year in South America and I got bored of having the same convos as well. "Where you from? How long you travelling for? Where you been?" blah, blah. I also know what's it's like to question your life. That's half the reason I left Australia in the first place, to work out what I wanted to do. I didn't. I went back to the same kind of job as before and escaping actually came later. I don't suffer from loneliness though even though I was/am alone most of the time. That is not something that's really ever affected me.
And yes, Germans are everywhere. But so are Australians.
Yes but particularly here in Sri Lanka,Germans and Aussies second
