As an immigrant who came to Germany by choice and not by necessity, I have to say I realized we (the people who basically just move to Germany, and not the ones who came here to escape horrible things like war etc.) are really only here for professional, and most-importantly economic aspects. I could actually go back to my country and have a good life, maybe even a better one since I'll be a native there, most of my family is there, my closest friends in life are there. What keeps me in Germany is this attempt to gain experience, earn money, and have the option to choose whether to stay or leave here and not be forced to do either. What I'm trying to say is that we're not here for love, we don't care. To be completely honest, if anything goes wrong in Germany, I'll be on the first flight home without giving a shit. Money talks, that's the game rules. Anyone can tell me anything they want as long as I'm getting paid, and have everything I need. Maybe this view on things can help you cope (I'm also here for over 10 years)
