It's A (not so) Wonderful Life

Headmaster Snape is at the end of his tether. The world hates him, he's had it up to here with enemies on all sides; and he's got nothing left in the tank to give. On the verge of taking his life on a cold winter's night atop the Astronomy Tower, he learns a very important lesson. Rated T for discussion of Suicide. Inspiration taken from the film: It's A Wonderful Life.
