Nobody wants to rock their own life. But, on the other hand, when your life does get rocked, it affords you a certain level of emotional honesty. It liberates you to be who you really are.
You have to look at what you have right in front of you, at what it could be, and stop measuring it against what you've lost. I know this to be wise and true, just as I know that pretty much no one can do it.
