"Stranger" - A Joanlock fanfic

Chapter One

The summer passed, and autumn was obviously on the way.
Jamie Moriarty was sitting next to the window, looking at the pouring rain.
On the other side of New York, however, Joan Watson was preparing to move out of the Brownstone she had lived in for the past two years.
What did this really mean?
She didn't just want to leave Sherlock behind, but she did want to lead a normal life.
So how was that possible?
Although she cared about Sherlock, the fact that she got abducted two weeks ago was still super unsettling to her.
He walked into the room, and looked her straight in her brown chocolate eyes.
"Hi"
"Hey"
This was sadly the only thing they said to each other in the past 24 hours.
She remembered the first time she was going to move out. Well, she never did.
Was this really worth it?
No. It was not. And in a few hours she was going to know why it was not worth it.

Walking into the brownstone, Joan had a feeling something was wrong.
Everything was just so quiet.
Did he leave?
Sure, she had to unlock the door, but he could just not be home, right?
"Sherlock?" -  her voice echoed, and there was no reply.
"Sherlock?!" - she literally screamed again. Okay so he obviously was not there.
As she walked into the kitchen, something caught her eye.
It was a note.
A suicide note?
No, it couldn't have been. Sometimes her thoughts were just too overwhelming.
She opened the envelope and started reading;
"My dearest Watson,
I am writing this just in case you come by the Brownstone.
I'm glad our collaboration has lasted for two long years, and I'm glad this is where we are wrapping up.
I guess this is the end, really?
Wow, it just seems so strange.
Now you're just a stranger, who holds all of my secrets, and all of my pain.
I apologize, and I assure you, its not you, it's me, and you don't need me. Sorry."
Suddenly, she was so sad and so mad at the same time.
Her throat started tightening as she felt the tears coming up.
She felt sick, sad, confused, alone and even scared, at the same time.
Was this her fault?
How was she going to move on so quickly?
She started breaking inside, and sat on the floor, against the wall, literally drowning in her tears. Even after all this, there was no wailing or sobbing. The flow of the tears was steady, but she was struggling.
