Well, its not uncommon for objects to conjure bad memories. He may have tried to commit suicide, but that doesn't mean he remembers this moment fondly. It seems like he's wants to forget whatever happened to him.

Honestly, I think our protagonist suffers from sorts of depression. After the suicide, his parents thought it would be best for him to relocate and give him a fresh start (word travels fast in school, it would tough to be "the cutter" kid)
