Peter Pan: Suicide and Purgatory?

One of my friends told me that the true story of Peter Pan is a about a boy who commits suicide, then he is some-what trapped in Purgatory (Neverland). Then he goes back to the real world to get "Wendy" or whomever to commit suicide as well by jumping from their balcony and entering purgatory. I haven't found this story online, but has anyone ever heard of it? It sounds horrible. Is it really true? Thanks.
