Okay, so as I understand... your current position is that you're a high school graduate, your parents are protective and so are stopping you just going out and getting a job, so you're presumably living with them while you attend community college. You've done jobs on Fiverr and similar, and you're working on a comic.
As far as I can see, you're doing everything right for getting into the industry from a background without contacts.
Instead of troubling yourself with making money from your writing to pay an artist at this stage, I suggest you focus more on building your portfolio. Try searching online for "Comics Anthology Submissions for Writers" and you should find a bunch of them that will take submissions from a writer and pair you up with an artist for that short project. See if you can get artists on places like the Tapas forums, deviantart, LinkedIn etc. to work on short portfolio pieces of say 10 pages.
If once you have a few good samples, if you can find a place to get a professional script review, like a comics event, or somebody who takes online submissions, do that. Also getting a proper website for your portfolio and profile, rather than a google doc would really help, so if you can sort that out, that would be good.
If you want to make money from your writing while building visibility, you could try to get gigs writing for social media, write a blog or similar and use that to build a following, make youtube videos or a podcast, or you could write serialised novels on places like Tapas, Wattpad and Radish, which could all potentially both make money, but more importantly will build your personal brand and visibility.
If you want to work as a games writer, the easiest way in is weirdly to either become a games tester and work your way up from there, or to learn to code or use code-free or code-light game making tools, like twine, Ren'Py, RPGMaker, Game Maker Studio etc. to start making indie games with minimal art assets, and selling or distributing on itch.io and The Humble Bundle. That or learn to code to pro level and get work as a coder. It's a really different path to writing comics (unlike drawing comics, which tends to overlap with games a lot more).
Your writing samples look solid. Grammar needs a little work, so maybe get on sprucing that up a little, but overall, I think if you keep going you have good odds, so hopefully some of that advice works for you!
