post-erasmus syndrome

What is it exactly? does it exist? Phycologist say that it is true, there is a kind of sick called;post-erasmus Syndrome; where everything remember you to your erasmus country. It is just when you go back to your own country and do not like your friends, your city, your language and definitely to back to your routine.

I have two months more here but i am in contact with my old friends and told me it is really bad sick. Also it exists a list where you are able to identify the syndrome, looking it carefully and check if you stay in the same situation.
