Honestly, I think it's better to develop your own strategies. Things that don't feel trite and that actually work and that you're actually willing to do.

It's funny though, because one way I dealt with awful nightmares that I've had all my life was to use them as a base for short fiction stories. Obviously not all of them turned out happy or even made sense, but it gave me a sense of control to get some sort of positive product- a super creative story- out of it. Of course I did that on my own, not because a therapist told me to, so again I say find what works for you. Just whatever it takes to address the issue in your own way.
