Questioning lessons

Sometimes God puts really good people through very difficult times to test them and strengthen their faith.....well atleast this is what the grown ups always told us when we were young and went through something bad. I see bad things happen to a very good person and I wonder why God would make such a great and wonderful person go through such difficult times. It's hard to straightforwardly believe in what the grown ups told us when you see this happening to someone you care about so strongly. This is when you start questioning all the lessons they taught you.

I do all I can to keep this person strong and maintain her cheery and delightful take on life....but I worry that I'm not doing a great job. Ironic that someone as fed up as me has to be a pillar for someone who has given me strength and resilience through so much.
