Change is the law of nature. Everything that belongs to this earth must change. And you should accept these changes as a part of life. Therefore, wherever you get attached to, you are likely to be unhappy due to possible loss of the attached thing, person or place. Stop fearing the loss. Some risk is always there in life; no one can avoid all risks. I would go one step further to say that taking some risk is necessary for your growth.
In the circumstance it is best not to be attached to anything. You should be prepared for change as they say change is the only thing which is constant. Except that, everything else changes.
