trying to get into publishing

i know a lot of people make posts like this but i'm feeling really stuck.

im 25 and i graduated in may with my bachelor's in creative writing and literature, and i've only had one internship in publishing last fall. otherwise i worked on my school's lit magazine but i've applied to internships and haven't gotten anything else. admittedly, i applied to a lot of the big 5 internships and i should've focused more on indies but i feel like i'm never gonna get in. i have an interview for a grant writing job tomorrow but i'm so scared if i get it because it's not something i actually want to do, but i need a job. i feel like im running out of time to get internships though because a lot of places require you to be a student or recent graduate.

i don't know, i'm just wondering if it's unrealistic or what should i do? i'm in the surrounding area of nyc btw
