My life is taken over by something wearing my skin.

Hi. I don't really know what to start with. This all kind of just, happened out of nowhere. I'm really confused and scared. Honestly, any help here is appreciated because my life is in shambles.
My name is Darla. I'm 18 years old. I'm going to college to get a doctorate degree to be a psychiatrist. I work as a waitress at a local bar. My days are long, and I often don't get home til late hours. I live with my parents, I'm an only child.
About a week ago, I got home around 2:30 in the morning. I got to my door and dug around in my purse for my keys. Strangely, I couldn't find them. I figured I must've left them at the bar, and cursed myself for forgetting them... again. I brought out my phone and called my parents, hoping for an answer. Sadly, no dice. I decided to call my friend Nancy to say at her place for the night. She's a regular at the bar so I knew she'd still be up at late hours.
The phone rang for a moment before Nancy picked up the phone. I let out a sigh of relief.
"Nan, it's Darla. I left my keys at the bar again, do you think I could crash at your place for the night?"
The line was silent. This was strange. Usually Nancy always starts chatting once she hears my voice. She's rarely ever the quiet type. Getting worried, I'm about to say something before her voice rings in my ears.
"Uh. Listen *******, I dunno what you're trying to play but don't call this number."
I was dumbfounded. What was she talking about? I've called her plenty of times and I know she has me in her contacts.
"Nan, what? It's Darla. Look, if you're trying to be funny I'm really not in the mood. I told you I left my keys at the bar and-"
"Darla called me today and said she wasn't going to be at the bar tonight." Nancy interrupted me. "I was there all night and didn't see her. So quit ****in' playing with me."
The line went dead. I stood with the cell phone still against my ear in total shock.
I had been at the bar til closing, I know that. I saw Nancy there, I even spoke with her a few times. How could she think I wasn't? To make sense of it, I convinced myself she was drunk off her ass and having an episode. But now I had to pay for a motel room for the night, which sucked.
That night at the motel, I had a strange dream. I woke up to someone looming over me in my shoddy bed. It looked like a woman, with long dark hair. But the room was so dim I couldn't see her face. She said nothing. And even though I couldn't see her eyes, I could tell she was looking at me.
When I woke up, I checked around the small room to make sure no one was there. I combed through the closet, under the bed, I even looked under the damn rug I was so paranoid. In relief, I turned back to the bed to gather my things when I saw it.
The open window. The cheap curtains fluttering in the slight breeze, and the wind tickling my cheeks. It made my heart stop. That sickening, gutteral stab of fear that launched throughout my entire body just by seeing a ****ing window. I packed my **** and left there immediately. I had to get back home, this wasn't right.
I have no car, so I walked to my house around 10 AM. I approached the front door and rang the doorbell. The little chime rang quietly outside, filling me with peace as I realized I was home. My mother opened the door, and I gave her a huge smile.
"Mom! Hey, sorry. I left my keys at work and couldn't get in last night. I stayed at the motel but-"
I stopped mid sentence when I noticed my mother's expression didn't change. Her brow was heavily furrowed and her light eyes squinted, creating those wrinkles around her eyes. It was like she couldn't even see me, or was looking straight through me.
I waved my hand in front of her, and she remained unfocused on my presence. Then, she suddenly shut the door in my face, leaving me out on the front porch.
I could only stand there, staring at the damn door that my ****ing mother just slammed in my face. I couldn't believe it, and my mind began whirring with solutions. Could she be mad at me? What did I do? Am I being disowned? All of these made more sense than me suddenly becoming ****ing invisible.
And then, I dunno what made me do it. Maybe it was just pure desperation and the fear of whatever the **** was happening to me, but I decided to start peering into my own home through the windows. Everything was in place, nothing seemed different. It was all how I remembered it when I left for school yesterday, if not tidier. I didn't know what I was looking for. Some type of explanation for my situation within my own home I guess. But, then, my eyes rested in the dining room. What I saw made me glue my eyes to the window and made my body tremble so hard that I almost collapsed onto the porch.
Inside the dining room was my parents having breakfast. And sitting between them was me.
Except, it wasn't me. I could tell. Getting a good look at her, she definitely looked exactly like me in appearance. Aside from a few things. Her smile was wide, too wide. Her mouth in a giant curved line, struggling to maintain shape. It was so wide it seemed almost painful to keep smiling that way. And her eyes were lifeless. Her dark, dark eyes were glossed over and hollow. No emotion in those irises despite the wide grin she sported.
And that wasn't even the most frightening thing. In an instant, her dead eyes flickered to the window I was pressed against. And she saw me. That THING saw me. Not even my own mother saw me but that Thing locked eyes with me. Acknowledged me.
And it smiled.
It smiled with that wide, inhuman grin, exposing it's teeth. MY teeth. It even had the little chip in my front tooth from when I fell playing soccer when I was fifteen. She had everything down to a T, she was almost an exact copy. And the way she smiled at me, kept that unnerving and corpse-like stare that bore into my very soul, allowed me to kindle my fight-or-flight instincts. I ran. I ran so ****ing far away from that house and that ****ing THING. The thing in my skin, the thing running my life.
I had to take money out of my savings to buy myself a ****ty apartment downtown. I tried going to work but my boss couldn't see me. And when I called, he couldn't even recognize my voice.
These past days I'd go and watch my skinwalker, if that even is what IT is, go with my family. It does things that I'd never do. It goes to church with them on Sundays, I'm agnostic. It speaks with everyone it meets in my voice, I was never that chatty. And it stands so refined and perfect that it shouldn't be humanly possible to maintain such perfect mannerisms.
How can they think that it's me? It's nothing like me, it CANT be like me. Don't they know me? Doesn't anyone know where I am?
And believe me, I'm ****ing terrified of this thing. Not only is it taking over my entire life, it stalks me while I sleep. I see it in my window at night. For ****s sake I'm on the sixth floor, I have no idea how it could even get to the ****ing window. But I see it with that inhuman smile and those hollow eyes. It stares at me. It grins at me and ****ing mocks me. And I swear some nights I can hear it whispering unintelligible words into my room and poisoning my mind.
Please, I need help. Does anyone know me? Do any of you remember Darla? What do I do? How can I get rid of it? I'm so scared of fading. Please don't let me be replaced by a monster. I just need something, any type of help I can get.
I'm going to try and keep updates. But if I stop posting, just know that if you ever see Darla, it isn't me.
