Nobody can suggest a country without knowing about your career and personal goals and aspirations. Even if you find a country suited to you from this thread, you need to first find a job (or university) to afford any kind of life there. Having a master’s degree doesn’t entitle you to a job in a country of your choice. If you think you are miserable now because of loneliness or lack of a social life, wait until you are jobless and lonely in another country. Also, no country is going to accept an expat just like that. My words may seem harsh, but that is the truth. It would be easier to find a job in Germany than anywhere else at the moment for you. Going back to India is another option, because I believe India is going through a huge growth phase with plenty of opportunities for almost everyone.
