Accept the worst. Take your pain as challenge -- challenge to tolerate it fully no matter how hurtful it is. Acceptance frees you from the burden of fixing responsibilities or blaming your self.
Take stock of what you have -- You are not dead until you actually die.
Silence the negative chatter of your mind read my hub on that topic and try dropping the mental baggage.
Remember, there is always another day after darkness of the night. Wait patiently for the sun rise.
