Sorry! Culture divide possibly. Sister is a gentle, sweet and loving religious - no trace of bitterness or regret. Joyful in life and circumstances.
All that is negative and not good in our world comes about through God’s Permissive Will (the theological term for what God permits). All that is good and positive in our world comes about through His Direct Will.

"We must distinguish between God’s positive will, and His permissive will. He positively wills all the good that happens. Suffering He permits to occur, and this only when he foresees that good can result from it. He positively wills that I should be holy. If He foresees that I will make use of good health to sin and to lose my soul, He may mercifully permit my health to be ruined, and thus lead me to Him where He would otherwise lose me. There would have been no diseases had men not sinned. God did not will sin, but having made men free, He permitted it and its consequences. This permission was a less serious thing than would have been the depriving us of our freedom. "
A general comment addressed to no one in particular: please do not misconstrue the above quotation from New Advent. If a person looses their health, it is not necessarily to avoid some negative factor if God had willed that good health be retained throughout life.
As the quotation from the Catholic Catechism states, we cannot categorically know the reasons God permits or wills whatever He may in the life of a person. We will only understand in Heaven.
