I believe I will fail my a levels and I don’t know what to dk

I picked physics maths and chemistry but in my first year of college I began dealing with a lot and had a lot of absences, I would leave all my exams blank and so kept scoring very low. In my second year I tried picking myself up and started focusing on maths and ended up finishing year 12 maths. But when I realised I’m still failing chem and physics I tried revising. I ended up having to deal with a lot in my second year and kept getting distracted. It's now April and there’s only 12 days left of April. My first physics exam is in may. I know some of the content but a small amount and I can’t do exam practise because I don’t know all of the content. Idk what to do, my head hurts from trying to do 7 hours of revision a day and I just can’t take it. What do I do?? Do I give up? Do I keep trying or give myself some peace and give up
