(Obviously this is all sillyness you're generating to entertain yourself--a parrot that gave up on pulling its feathers and retreated into its mind--fictional characters don't have the same rich internal experience that you can directly observe having. (Well, unless, perhaps, they're animated by readers with sufficiently active imaginations...?)
Not to mention that any story in which you played a starring role would be... unreadable, for many reasons. Your life is unrelentingly tedious, and you're unlikeable. Empirically. (And, to rebut the obvious counterpoint apropos Harry Potter, you're not a high-minded hero who only knows Dursleys; you're petty and vicious. You exist in the proximity of group discussions in Language Arts class, and trawl the comments on Line Webtoon; antiheroes--in the original sense of the word--make your age cohort see red.)
And you've never actually read anything using a device like this. To be fair it isn't needed: the standard first-person-limited thing with its acceptable breaks from the word-for-word monologue wherever you need to include the main character's background knowledge (and what they think and feel about it) probably makes for objectively better literature, as long as you can do it unobtrusively; something something art is meant to be truer than life. Don't get the words you're writing in the way of your own story.
And you're not sure that the standard first-person-limited thing is generally supposed to be taken as an internal monologue anyway; something like half of people don't have internal monologues and people still write books about them. And, if you recall correctly, only 60% of internal monologuers use the literary-standard first-person pronoun of "I"--and you aren't one of them. So if you were a viewpoint character, you'd need your raw thoughts edited anyway, if only to match the house style.)
