Rough year and not sure what my next move should be

28TF here. I've had a really rough year that has caused me to lose a lot of hope, and I want to try my best to turn things around, but I need some guidance. I'm currently working a part time cashier job at my local supermarket and honestly I can't stand it, and have been trying to leave for the past year, but have had absolutely no luck. Standing in the same tiny area, repeating the same conversations, doing the same motions everyday for hours has been terrible on my mental health, and I need to get out asap. I've worked a few other places before, but they've also been in the realm of fast food/retail, but they haven't been as bad on my health. I'm really not sure how to move on from this job, as I don't really have any big marketable skills or even a college degree, which definitely doesn't help in the current job market. I'm not sure what I even want to do in terms of my career, I just know what I'm doing now isn't it. I do know that I'd like to be self employed someday though, whether that be through creative work or otherwise.

I also just lost my car a few months ago and finally got finished dealing with the insurance, but still have just under $2000 left to pay off the loan that I thankfully don't have to pay off until 2028. Me and my gf have been carpooling for work with her car so not having a car hasn't been a huge problem yet, but I definitely need to save for another one asap, especially because hers isn't the most reliable. I also have a little under $2000 on my credit card as well that I need to pay off, but I'm not sure if I should be focusing on that rn too or if I should just focus on the car.

I think having an outside perspective would be really valuable, so if any of you have any sort of advice, I'd love to hear it.
