my SHORT AND SWEET ANSWER
When you decide to stay or go, write down your reasons for staying and going, laminate it , date it and put with your personal records.
If in a year or so your life turns to sh#t and you regret your life decision, then you can look back on the reasons for leaving flying ( or whatever it is in life) and say to yourself that you made the decision based on your feelings at the time.
WE ALL HAVE REGRETS, BUT NO ONE CAN PREDICT THE FUTURE.
