I’m in my last year of school and have exams at the moment 2 test tomorrow that go towards my end of year score and all I can think is I can’t do this

I am sitting here thinking how fucking pointless an essay is or a test like yes they will give me a grade to to you university but that is I could be out experiencing the world having fun living instead of being trapped in my room looking at fucking enzymes and photosynthesis

How do I get to the point where I study as I want to do well yet I just don’t see a point also I’m like 99% sure I’m suffering from depression as life circumstances have made it impossible for me to function like a normal person.
