Should I leave sixth form and start an apprenticeship?

Ok, so I’ve had exams throughout year 12 and now it’s coming to my year 13 exams but I just feel so overwhelmed and anxious about them. It’s making me start to think about how I don’t actually want to use these subjects at all so I think it’s pointless in staying. My mental health has been awful because of it and I just had an entire week off as I just couldn’t face going back. I’ve been looking at different apprenticeships and applied for them but I feel like if I leave sixth form I’ll just have to stick with a regular job for the rest of my life lol. What should I do?
