What were the ambitions and goals you had? You mentioned creative pursuits. And how old are you? That's my only questions for you.
I'll just leave you with a few comments and anecdotes that hopefully help broaden your perspective. First, if you are pursuing a creative field, I hope it works out for you. I've always been heavily interested in multiple arts, but never had the guts to pursue it as a career. I'm not near any major cities on the coasts. I'm also from a poor family. I always got the sense that working in a creative field is like rolling the dice with your life. If it works out, you have something closer to a dream job that you can genuinely enjoy. If it doesn't work out, you have nothing. I knew some people that focused on the arts in college, and all of them came from rich families. If my artistic pursuits didn't work out, I'd be a beggar in Medinah as well, and I just couldn't risk it.
Anecdote #1: My brothers were in the same boat, but
committed to staying in a band, just not going all in on the band and trying to tour the country full time and get signed. They stayed in school and got normal jobs. They can still play shows locally, record music in a basement practice space / studio they set up, and self-publish whatever they want online. A lot of art can now just be done on the side while you hold down a normal job. You can be an independent author that just puts up stuff on Amazon, or sell artwork on your own website and so on. One of my friends makes his own jewelry and cuts stones at home, and just posts about it on facebook. It's gone well enough that he just does that now and watches the kids at home. The founders of Bioware were medical doctors, and then after that, decided to gamble on gaming. Some people roll the dice on their whole life and it totally pays off in the best way, but there are other routes to consider if you're on the verge of talking about homelessness.
Anecdote #2: I knew a guy who was really a decent dude, smart, just kind of immature and unable to figure out what to do in life. He liked film and wanted to be a filmmaker. He loved Egyptian history and wanted to be an egyptologist. He didn't really have any guidance or help from family, and no one wanted to just crush the dude's dreams and call it a fantasy. But maybe if someone did, that would have stung, but actually been the guidance he needed. He eventually, years later, figured out how unrealistic he was being and focused on a 2 year associates degree that allowed him to get a pretty good middle class job. He's living comfortably and doing just fine.
Anecdote #3: I worked with a nurse who didn't even decide to go to school until she was 50, after getting divorced. She got her RN degree in a 2 year program, and then took a job in Hawaii. Just changed her whole life at 50 years old.
None of it is easy though, and you might fail multiple times on the way there. But you have no choice and need to find a way to support yourself so you're comfortable. You can either take the risk on a creative field, or keep creative pursuits alive on the side while working a more traditional job. And financial independence is how you mature, gain self-confidence, and improve your dating / family prospects. You're not unable to do any of this, you just have to get hardcore and fight for it for a few years, starting ASAP.
