If ever you feel discouraged, distraught, dejected, or downright depressed... I'm sorry, there is nothing that I can do for you.
However, some books that I have read, such as the Bible, would suggest that in these difficult moments you are actually in very good company. I won't pretend to understand what you are going through, but in the spirit of friendship, I do want to share just three brief examples of individuals who triumphed over adversity. These three individuals have at least two things in common: they each experienced debilitating difficulties, and they each triumphed over adversity through faith in God:
The first is Jack Rushton, the second is Nick Vujicic, and the third is Tom Dobson. Perhaps you will find something of inspiration in their stories, and when you triumph, others are sure to find inspiration in your story as well.
"Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? / As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter. / Nay, in all these things we are more than conquerors through him that loved us. / For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, / Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord." (Romans 8:35-39)
