I'm tired of studying

Ok so I have an exam tomorrow, it's history, and I can't bring myself to study. Today I had math and even tho I hae when I don't understand it I didnt find it hard to bring myself to study. But now I can't even read one sentence that I just want to quit already.

For me history has always been hard, everytime people say it to me they're like " you just have to read it a couple of times" no I can't. I really fin it hard, complicated and confusing. My classmates told me to "just cheat" but I can't "just cheat". Even if I wanted to I don't even have the energy to make a plan for cheating, it's just so exhausting.

It's not even about distractions, i shut off my phone and isolated myself from everyone else but I still have tto read a singular sentece a thousand times before actually getting it. It feels like I'm just seeing the words not reading. I honestly was going good at school this year and now I'm just stuck here, it's exhausting. I have headache but more than ache it's just like I can't see straight anymore.

I'm probably just let this test fail hoping for a not too bad grade and do better in the next one.
