From Letters of Note:
Early-2006, during a bout of depression, a young lady by the name of Crystal Nunn wrote a desperate letter to Stephen Fry. Says Crystal:
“I had no idea who to turn to. But I really needed someone to turn to and to ease the pain. So I wrote to Stephen Fry because he is my hero, and he has been through this himself. And low and behold, he replied to my letter, and I will love him eternally for this.”
Mr. Fry's wonderful reply can be seen below.
