All I ever think of is Dante's Inferno when I hear suicide.
Seventh Circle (Violence)
The seventh circle houses the violent. Its entry is guarded by the Minotaur, and it is divided into three rings:
Middle ring: In this ring are suicides and profligates. The suicides – the violent against self – are transformed into gnarled thorny bushes and trees and then fed upon by Harpies. The trees are a metaphor for the state of mind in which suicide is committed. Dante learns that these suicides, unique among the dead, will not be corporally resurrected after the final judgement since they gave away their bodies through suicide; instead they will maintain their bushy form, with their own corpses hanging from the thorny limbs. The other residents of this ring are the profligates, who destroyed their lives by destroying the means by which life is sustained – i.e. money and property. They are perpetually chased and mauled by ferocious dogs. The destruction wrought upon the wood by the profligates' flight and punishment as they crash through the undergrowth causes further suffering to the suicides, who cannot move out of the way.
