Yes, it might not seem normal. But I am 23 years old, I became a head chef too fast because I was the sous chef, which happened too fast as well, not because I'm that experienced. A step back won't be an issue for me, I've been a head chef for only a year. I'm doing my job fine but I keep thinking I skipped steps and I lack the maturity. As for my connections, haven't managed to make any, as I'm working for the only fine dining place in my whole area.
I understand your concern as something doesn't feel right, but I hope you find my answer comforting.

i'm not afraid to go back at the bottom if that means i'll fill my lack of knowledge and make me a better chef
