Some good advice here, some snarky comments too.
It's really important to find something with real job propsects at the end of it. If you've got the grades to shoot for a degree later then do that. If not then a skilled trade like joinery, plumbing or electrical will pay well enough for you to live a comfortable lifestyle.
I'm an electrician myself, I was like you with no clue about what I wanted to do. I wasted my youth really, drifted in and out of work, in and out of education, and when I finally came to my senses I retrained to be an electrician.
It wasn't something I had dreamed of doing, I wanted to work with computers too. But it was not to be and I am very happy and comfortable in my career now.
Just understand that you work to live, not the other way round. Your job doesn't have to be a dream job, it just has to pay the bills.
