Be the future

Haunting me, my past is haunting me, my past has been haunting me, my past will always haunt me. Who is a person but a combination of all his happiness, pains and emotions? So in some way, a person is no more than a combaination of his past, his memories, his experiences.

So, if a large part of that experience is pain, sadness and sorrow, wouldn't those experience be a part of a person and it's impossible to separate the person from those experiences.

It is easy for people to say "Just forget about it, it's in the past, move on, look ahead into the future". In an ideal world, it would be the perfect solution, and everyone would be happy and no one would feel sad after the initial instance. But this is the real world, things don't happen that way, people get depressed long after the cause of the depression. Pain is long lasting, and great pain seems to last forever.
