Unfortunately you need to feel the pain (cry, scream, hit a pillow), sh will just create more pain for you. Sit with the pain of the "present moment". You have no power over the past- it will just haunt you and the future is not here yet... Plan for the future if you can, however don't distress over it too much, because eventually the future will also become your present moment. Seeing that you're in a considerable amount of pain- only deal with the problems that arise in the present moment, ultimately that's all we have control over anyways.
