When I was depressed I had perfect trust in my ability to predict events, it was just that no matter how much I tried I couldn't predict a future where I weren't constantly in agony. I got over it by letting go of most things that were hurting me like friends, family, dreams etc. So now I live a fairly unassuming life but I am content. It might sound a bit boring but it is much better than living in agony every day for the rest of your life.
