I get optimism now. I understand the need for it. Sometimes you can’t afford to be pessimistic or even realistic about a situation. You can’t afford considering the worst possibility. It cripples you to even momentarily think about it. It does not exist. Life is all happy endings. Your situation is the exception to the rule. It’ll never happen to you. Repeat this to yourself. Repeat it so you could wake up in the morning, go to work, eat, fall asleep, and be able to continue to breathe.
