I am a Extra in the Movie of Life

I’m what you’d call a side character a side kick a background character an extra. I'm there for comedic relief the story could easily exist without me. The hero only calls on me when he needs something.
“Hey Robin.”
“Whats up Batman?”
“Can you help me clean out the batcave this weekend.”
“Of course but when can I help you fight the Joker?”
“Robin if anyone’s going to defeat the Joker it's going to be me. I’m Batman and your just my sidekick.”
I'm the uncredited extra you walk past in the hallways never noticing. Did you notice that I didn't have one line in this movie? Probably not because this isn’t my story it's yours. I’m living in the background of your life.
I'm there to move the story along or say something stupid and leave. I am only in on scene. I am the first character that dies in a horror movie the one you call stupid but you don’t even know my name. All you know is I shouldn't open that door. Oops JUMPSCARE. Boom I’m dead in the first five minutes of a movie that not mine. My death is used for comedic relief. My death is just a tool to move the story along it didn’t matter in the long run.
I'm the kid that cries in the back of a classroom and one one notices but why would you look at me when you could look at Scarlett Johansson. I am an extra, forgettable and irrelevant and yet my mom still cheers the loudest when my character’s name pops up during the credits.
She cheers For Bus Driver 2 and Bank Robber 47 and Dead Body 10. She cheers for Socially Awkward Teen 3 and Sad Boy 7. She cheers so loudly sometimes I forget I don’t even have a name. I am just a tool to make them look better.
The show would go on without me. All the main characters would be fine without me. I don't matter to their story I’m just ordering a coffee and crying in the background and no one notices the cappuccino the tears or me .
I am an extra in the movie of life. I am an extra in the movie of my own life. The spotlight is never on me it. I am an extra in the movie of life.
But my life isn’t a movie and i can’t be an extra in a nonexistent movie.
Even still I can't erase these feelings,
I feel worthless
I feel replaceable
I feel like i just blend into the background
I feel like I'm nothing
I feel like I'm a nobody
I am l a side character a side kick an extra.
I try to tell myself that I am important but i only have ten seconds of screen time and that doesn't seem important to me. I try to tell myself the they protagonist needs me but do they really need me? All I do is be there, thats all.
