I don't think it has anything to do with deserving, or punishment, or anyone's entertainment. I believe that there are reasons why we each experience the challenges that we do. We often won't understand why things happen, or why things are the way they are. But one promise God has made is that none of us will be given more than we are able to make it through. So you can at least know that even though your struggles are intense and painful at times, it won't be forever, and you wouldn't have this if you couldn't handle it. Help will be provided when you ask in faith. Nobody ever said you have to get through it alone.
