18yo Student Stuck in Non-Tech Job, Need Advice on Internship & Career

I'm an 18-year-old first-year college student working part-time at an IT company, but my role isn't tech-related. My boss promised me a tech internship if I learned C (I've completed 100+ C programs and know Python). Now, I'm learning HTML, CSS, and JS to strengthen my skills. However, my boss seems to have ditched me on his promise. Others in my company got internships without even knowing basic C, so I feel it might be because I push him for my delayed salary (₹6k part-time/₹12k full-time). My family isn't financially stable (my father is paralyzed), so my mom insists I chase him for payments, but I feel ashamed doing so. I'm overworked-after my job, I teach kids for extra income and continue learning coding. I've got a 2-month break now to focus on exams and plan to master HTML, CSS, and JS during this time. After that, I'll try again with my boss and other companies for internships. My concern: Will this be enough for a tech internship (paid/unpaid)? I feel a non-tech role for 3 years won't add value to my resume, but a web dev role would. What should I do? PS: Sorry for the rant, but I'm stuck and need advice.
