Also tried this version but am unsure which was better. 'Helping heal the hurt' seems corny.

I left a shadow for some time which disappeared but once was mine I left my mark upon the earth a temporary scar on dirt. It's not about a permanence  it's in the actions that you take it's making someone smile again it's recognising your mistakes. Remember not to be afraid before you were, you weren't you're only going back again what's learned will be unlearnt.
