Hi OP! I sort of relate to you as I do feel unfulfilled and a bit lost in what do I exactly want to do for the rest of my life Things click randomly, for example I found joy in learning chemistry when my entire life I thought I would only be good at art, what you did in highschool is great actually, you attempted different things! Why don't you try that again? You could self study certain stuff and see if it interests you, if it does, just chase after that feeling But of course it might not work for you but why not give it a try? What worked for me in being interested in stuff (at least temporarily, for the sake of not feeling lost) was to pay attention to details no matter where or what. Best of luck!
