Sherlock x depressed reader

Chapter one

-Alexander-POV-
"ALEXANDER SIR! WERE READY!"
i look at my men and women. even the ones who've used me give respect. 
"REMEMBER HISTORY HAS ITS EYES ON YOU MEN!"
They nod and solute. i turn and see my dad walk over and slam me against the wall of the trench.
"Little bitch."
he slaps me and all my courage goes away quickly as i fall on the ground. he pulls me up by my hair and i shoot awake breathing heavily with tears in my eyes. i dig my nails into my arms, as i try to calm down. after a few minutes i get up and get ready for the day. i put on some jeans with combat boots and a t-shirt, leaving my scars on full display until I pull on my jacket. i put my long brown hair in a manbun and pull my hood up as i leave the old building I'm staying in. i fix my knife on my waist and walk around a bit. i tap my leg and a stray dog walks over with me. he's beautiful, large with a black coat, intimidating. i reach in my bag and give him some food, gently petting his head before i leave. I walk around and my mind is full of what i could wright. add to my law papers, maybe medical. i walk around with my headphones in listening to the Hamilton soundtrack. music helps to distract me from my mind. such a pesty little thing my thoughts can be. always so annoying. don't get me wrong, my mind is excellent. But I get bored sometimes. I see two guys pestering a girl. I don't even take my headphones (🎧) as i walk over and pull them off her.
"Bitch mind your own business!"
i read their lips and sigh as they try to push me but i swipe the first ones leg, standing with one foot on his back as i put the other in a headlock and hold my knife at his neck.
"Leave her alone."
The girl thanks me and runs off with her friend who came out of the store and I let them go as i start walking. i find myself walking by a park as i feel someone grab my shoulder. i get ready to flip them when i remember, children are here. i stop and turn around.
"Alexander Watson I missed you!"
I look and see Charles benit. We were trainees together.
"Hello Charles"
He's gained 115... not in a relationship, he's a therapist now? Hmm. I think about pulling off my headphones and decide against it. If I do it'll stamp up my anxiety, that's not safe for anyone. Charles is smiling brightly.
"How have you been?"
"Fine, you?"
"Tired,"
He chuckles.
"I've been with a man who's a complete arse all day"
I mimic his smile and he nods.
"Still got the swingy accents I see?"
I nod.
"It tends to happen when you learn more than two languages my dear Charles."
He laughs.
"So where are you staying?"
I shake my head.
"No money for that on my own, I stay at an abandoned apartment, I mean, who'd be stupid enough to share a flat with me?"
He laughs again.
"That's the second time I've heard that today."
"Is that so?"
"That it is my socio, Come with me."
I shrug and we start walking.
"So Al, hows that brother of yours?"
I shrug.
"He's as well as he could be. We don't talk much. I mean, I had a different father. So we didn't live together so, I dont really talk to him."
He nods and is quiet as we walk to a flat. He knocks. On the door and a small women opens it.
"Morning miss Hudson! This is my friend Alexander."
She smiles kindly.
"Isn't he handsome! Are you here for Sherlock?"
I chuckle and bow before i go back straight face, Charles doesn't correct her.
"Why, yes miss Hudson"
"It is a true pleasure to meet you my dear"
I straighten up and she smiles as she shows us upstairs.
"Would you like some tea?"
Charles nods and I shake my head putting up my hand dismissively. She nods.
"Just this once though, I'm not a maid!"
She scurries off.
"Come on Alex,"
Charlie glances at me as we walk upstairs and to a door.
"What had we said about wrapping your chest?"
I shrug and he sighs knocking.
"ITS OPEN!"
i hear a deep, smooth, frankly rather bored sounding voice call out. i pull my hood up a little extra as Charles opens the door walking in.
"Hello Sherlock!"
he says cheerily.
"Hello Charles, and..?"
he still sounds and looks bored.
"This is Watson, Alexander Watson."
Sherlock's eyes me as he looks at me quizzically and stands up.
"Watson, watson, John never told me about another..."
he looks me up and down.
"Brother."
Charles chuckles.
"Wow Sherlock, this is truly surprising. You can't even tell what Alex is!"
"What?"
"Anyway, i was thinking you guys could share the flat like you and John did."
I look up from the floor for the first time since we walk in.
"You know my brother?"
"Well, assuming he is your brother ye-"
He's cut off my John walking in.
"Sherlock I'm- ALEXANDER!"
he runs over and tries to hug me. i don't hug back. i push him away and pull down my headphones.
"John what do you know about Sherlock."
John gets ready to speak and i give him a look saying not to. the room goes quiet as i read johns body to see what he's thinking. he forgot i do this. he thinks Sherlock's like me. he wants to know if im still doing drugs.
"UGH YOUR SO BORING JOHN JUST LEAVE ME ALONE!"
i shout and pull my brown bag over my shoulder as i snatch Sherlock's violin without them noticing and go into Sherlock's room. shutting and locking the door.
-Sherlock-POV-
"What was that about?"
I ask looking at John.
"She reads people, but she thinks doing it when they talk makes it to easy."
still, why couldn't i read him?
"She?"
"Yes, She got mad because I asked a question she doesn't want to tell me about."
i nod and keep thinking. but why, of all people couldn't i read her? how did i think she was a guy at first? damn, what's happened?
