I wonder why I spend so much time whining when I need to be rejoicing and thanking God for all He does for me...and most of the time, without me even asking. When I get to the end of the day, I look back and see His hand in so many things I wasn't even aware of at the time.
Go to the library and get some books by people who truly have suffered untold hardship. Watch some movies about people who have overcome unbelievable abuse and torture. Listen to podcasts of people who have endured and even rejoiced in how the Lord has seen them through those deep waters they have had to cross, and high mountains they have had to climb.
Then walk outside, look up and down the street, and pray for the person two doors down. Also ask the Lord to show you how to help others overcome their hardships. Maybe it will make what you are going through a little easier to bear.
