I actually read a religious based book on anxiety once that said (secularized) "look at all the hard situations you've gone through and how you felt about them vs how you actually fared. Perhaps you could temper your current mood about the present in light of the difference between how things felt vs how they turned out." It's not absolutely most rational point, survivor bias and all, but it does have a point about not being excessively negative/anxious.
