Apply to lots of places, be honest about your experience. You might have to take less money for a year or two but you are still young. The first job is by far the hardest but the challenge of interviews never goes away because as you get more senior people expect more from you in the interview.

Do you just have code in Github or do you have an app running somewhere that people can actually interact with as well as the code for it on Github? If you don't have something live, push something live. Use Heroku or some other simple hosting solution if you want to get it live quickly.

You can also try to get involved with an existing substantial open source project. Try fixing a bug or adding a feature. Get advice from the project maintainers and work from there. That's as close as you can get to work experience of collaborating with a team. Get something merged to an OS project. And then when you interview you can talk about that experience so the company knows you can work with others to get production code shipped. You might have to log into IRC or Discord or send a bunch of emails to get started with the kind of direct communication necessary to do this. But learning how to take that kind of initiative is valuable in a company setting as well. If you do good work those open source maintainers could even become leads or references to help you find a first dev job.

Lots of people change careers into software development with less technical backgrounds than yours (I've met former actors, artists, lit majors...). You have much more than hope, if you're persistent you will find the job you're looking for, it just takes some hustle.
