Problems can creep up on you like a shadow. And, very slowly, they grow over time like a plot. This thought just came to me, so bear with me if I don't make sense. Anyway, everyone needs a shadow. They need to learn from their shadows to help them develop.
So, here's a personal rule I thought up when writing your conflict:
Every MC should have a shadow. And, the only way to get rid of the shadow is to turn off the lights, to stop running from the darkness and face what they fear. Head on. If your MC doesn't accomplish this in the end, then you, my friend, don't have a plot. You don't have a resolution, and you wind up leaving everything in the air.
You end up with unanswered questions, and readers who are scratching their heads.
