It's no fun being mistreated.
Regarding someone else's alcoholism, sure, I didn't cause it, I can't control it, and I can't cure it.
But things aren't always that simple.
A couple of helpful questions:
What decision did I make based on self that later placed me in a position to be hurt?
What might have I said or done that occasioned, elicited, invited, encouraged, or enabled the mistreatment?
Sometimes the answer to 'Why me?' is 'Why not me?'
Sometimes the answer to the question empowers me to avoid similar situations in the future.
