I think I’m addicted to studying

I have my GCSE exams this month and I’ve been feeling a lot of pressure. Many family members and teachers keep saying I should be aiming for top marks and all As in subjects and it’s putting me under tremendous pressure and I’m struggling really badly.

My problem is I cannot stop studying, I feel like it’s some compulsive addiction. I’ll wake up early to study and I go into school when no one else is in to study. Then when I get home I start to study straight away until 11pm. I have no free time at all, whenever I try to relax I start to panic and I have to go revise or I’ll go insane stressing. I can’t even sleep without not thinking about revising, when I try to sleep I just go over things in my head. I thought all this was normal until one of my friends pointed out that it was weird.Is there any way to overcome this?
