Iambic pentameter?

Well, first of all sonnets are generally fourteen lines and follow a specific rhyme scheme, but the lines you have fit the meter (iambic pentameter) except for the third line only has nine beats, and the fifth line has eleven. Iambic pentameter means that each line should have five strong beats and five weak beats (syllables) each, and they alternate (strong, weak, strong, weak, strong, weak, strong, weak, strong, weak- 10 total). May I suggest instead of "just" in line three you put "awful" or another two syllable word ("it is awful like a jungle in here"), and for line five how about contracting "you are" into "you're" ("you would think you're in a high school chick flick"). Those should fit the meter and still maintain what you were trying to say, and if you really want it to be a true sonnet then I suggest making fourteen lines and following a conventional rhyme scheme used for sonnets.
