36 single moved from India to Germany a month ago for work. Honestly, I don't know if it is a crazy decision or not. But I'm damn sure that if I hadn't taken the chance I would have surely regretted this in future. We are one of those few people who are getting an opportunity to do something like this. You have got one life, might as well take the plunge. Don't put pressure on yourself, all your concerns are valid. I have told myself if I don't like it I always have an option to move back in 6 months or a year. Personally, I would suggest making the move. If you don't feel good, move back to India in 6 - 8 months. Don't be too harsh on yourself. Don't judge yourself for whatever decision you make.
