Trust in Death | Reaper!Sans x Fem!Reader

As a 17 year old orphan, life's hard, but you have to deal with it.
You've been to several different foster homes, and at first every parent seemed fond of you and welcomed you with open arms. That is, until they started noticing your delusions, tales of ghosts and sometimes screaming bloody murder because the lady or man in the corner that no one could see won't go away.
As a result, you where diagnosed with schizophrenia.
You didn't like being called crazy, so when you turned ten, you kept your mouth shut about the paranormal, hoping you could stay in a home for good.
But then a ghostly figure starts visiting you.
He stands in corners, silently watching you, seemingly amused.
You where warned by ghosts to be wary of him, for this man was the Reaper of Souls.
And a comedian.
Who went by the name of Sans.
