unemployed pastry chef

Hey, I need some career advice.

I worked pretty hard to be where I am (to no avail) I come from an abusive childhood home & never had much money. I went to an expensive pastry school abroad and to afford my tuition I starved and lost 1/5 of my weight. Then I tried to get a good internship but couldn't afford to not get paid so I just worked at smaller cafes. I was eventually able to get a job at a 5 star hotel w 3 michelin stars, but the environment was too toxic I was only mentally able to stay for three months.

Recently I had issues with a visa not getting processed & I lost my job, leaving my fiance behind & had to move back to my home country. Most jobs are rejecting me and despite all my efforts I feel like they are right to do so. I lost all my confidence, everything I learned at the school is near forgotten because I never got to do fancy stuff professionally (until the hotel). But I also never got to learn traditional stuff back home. I still have a large student loan to pay back.

I make delicious stuff & I'm very creative in sort of a quirky way but my techniques are honestly pretty poor. I can't stay homeless without a job for too long. How can I improve realistically in my situation & what steps should I take in my career?
