$2K/month income, motel housing, limited savings — what’s the best path to independence?

I’m 21 and make about $2000/month working retail. I’ve been at the same job for around 2 years, working 5 days a week, 12pm–8:45pm (8-hour shifts). I recently got an interview for a job offering the same hours but about $3 more per hour. My current income is stable, but it hasn’t been enough to build independence.

For the past 3 years, I’ve been living in a motel with my parents. I contribute about $600/month toward the motel rent. My mom struggles with alcoholism and doesn’t work, and I help cover costs, which makes it hard for me to save or plan a way out.

I don’t have a degree, certifications, or a car. I do have access to public transportation, but it’s not very reliable where I am, so I often rely on Lime scooters to get around the city.

Some additional context:

Same job for ~2 years (stable employment)

Building credit for ~2 years (no major issues)

Very little savings because of living expenses and helping at home

I feel stuck because I’m contributing to my current living situation while also trying to figure out how to become independent.

Main questions:

Should I prioritize saving money even if it means contributing less to my family?

Is it possible to move out with roommates at my income level?

What would you do first if you were in my position?
