Lost after a gap year

I (19M) took a gap year right after graduating high school to figure out what i wanna do but now i’m lost. I always did great on standardized texting or the ACT but i felt like doing schoolwork was below me so my gpa tanked. i originally was gonna go blue collar, either get an apprenticeship or get an associates in automotive but now i’m considering culinary school. so yea LOST. everyone keeps telling me that i’m smart so whatever i do i’ll be good at it but in all honesty i feel stupid for not knowing what i want to do already. tell me what you did i guess or if you have any advice on finding career paths i appreciate it.
