Figuring it out as a cook

I’m a 17 high school student and I’ve been working in the restaurant since I was 15. I started off as a busboy and after 3 months realized I hated that so I asked the chef about working in the back of house and he said yes but I’d obviously start at the very bottom as a dishwasher. About a year after I started working then I went to Denmark to be an exchange student. I made a lot of shitty decisions and that combined with stuff happening back home caused me to be seen as no longer fit to be an exchange student. After 7 months of being there I was sent back home to my small town in Oregon which did not help things in the slightest. Luckily for me however the chef I was working for was being over worked and need someone to handle things so me being the reliable hard working person I am he gave me a premonition to be a prep cook. Since I was sent home early I didn’t have to go back to school since I had a transcript from Denmark so all my time was put into working and that’s what I’m still doing and I thought I’d be okay in working in this industry for the rest of my life which I still think I am but I don’t know if I have the skill or the mental fortitude to do this and If I do end up giving my life to this and it doesn’t work out then I’m fucked and I don’t know what I’m going to do.
