Amnesia Custom Story: Crueldatis et Tormentis, HELP NEEDED!!!!!!!!!

[BeforeTheMomentGirl]

So, hi... I'm beforethemomentgirl (Niwa)..
New to the forums etc, but that's not why i'm here.
I'm making a custom story (kinda) Yet fail at using the Level editor, as my PC can barely run Amnesia in the first place XD.
Yet I have this story, that I'd love to make into a Custom Story.
If anyone wants to co-operate, I'd love you!

A bit about the story:
You don't remember who you are (How original)
or where you are (Omg i'm SOOOOOOOooooo original (A))
You wake up in a bedroom, Nicely lit (No windows) You find a note in the study area, about a woman.
A woman called Lydia, she wrote about how her brother is coming to visit.
In the same room you find another note, (partially spilled with blood) From the brother of Lydia, how she's gone mad.
what will happen...?
I know :D
you dont >:D
Well... Goodbye ^^ and thanks already =D
