Driven from the Edge (слэш)

Harry Potter wishes he had never been welcomed into the wizarding world. Perhaps then he wouldn't have such a growing body count to his name.
One night, with the death of Sirius ringing in his ears, he finally decides this new world of his would be better off without him. Severus Snape believes differently.
Trigger warning for persistent suicidal ideation and self-harm tendencies. It's going to be a rough ride for both of them.
Likely a slow burn. Nothing serious will happen while Harry is underage and supremely vulnerable.
