I have wished that before but not anymore. I think every person & experience is valuable to your growth no matter how shitty they or the situation becomes. What we experience in the world is projected out from our subconscious beliefs & assumptions. These conditioned habitual ideas we repeat over & over instead of seeing with new eyes. We see the present painted by fragments of the past. Sometimes the truth of a situation is not really how we perceive it. If you can manage to look at it from another perspective you might actually learn to appreciate what you previously thought was horrible. That poison could then become the remedy.
