I recommend you read The Will to Power by Nietsche, to get a better grasp on what concepts like good and bad and luck represent.
It will be easier to read it from a outspoken nihilist like Nietsche since you don't like what you call new ageism.
You are responsible for your own feelings in this existence, but that doesn't mean you are alone in what you experience. You don't know how bad someone else had it so it's no use to compare. The nature of the lesson is universal.
