I need help

Ok. I'll summaries as much as possible. I have a biology exam in 9 days time, and a math exam in 13 days time. I cannot bring myself to study.

The thing is, I was someone who would usually get high marks, year 10 hit, and I started facing difficulty and my marks drifted down to 80% and 70%. The thing is, now that I don't get the high marks I want, I don't have motivation to do anything anymore.

I procrastinate, and waste time. I've tried everything. I've turned as many devices as possible off, signed off social media, blocked certain things on my laptop, but I still get distracted. and if I don't get distracted with a device, I would start doing chores or read.

It's not my attention span. It's that huge dread I feel every time I open a book. While I genuinely enjoy studying, but for some reason, since September, I've had no motivation to study. Right now it's late. I keep saying I'll wake up early to study, but I can barely get out of bed in the morning.

(also i have to mention that I do study, and i do understand he topics, just not as much as I want to)

My mocks are in 2 months time. My IGCSEs are 5 months away. I need help
