India, May 18 -- After living in Europe for five years, Karan Punjabi thought moving back to India would feel natural. Instead, nearly four years after returning, the Mumbai-based entrepreneur says he is "still not over it".

In a candid Instagram post that has resonated with many Indians who moved back home after living abroad, Punjabi opened up about the emotional difficulty of "reverse culture shock" and feelings of loneliness.

"I spent 4 years in France, did my master's in Barcelona, and moved back to Mumbai almost 4 years ago. And I'm just now able to talk about how hard it actually was," he said in his Instagram post.
