Increasing myopia alongside with pain.

Hey, I'm 17 years old. I discovered last year that I had developed a myopia. I saw a doctor and I got the prescribed glasses. It was a slight myopia, very slight one even. However, after only few weeks I started neglecting wearing my glasses. I felt nothing except some pain for several minutes every now and then. A year after, today, I discovered that my myopia has decreased on my right eye. I started to be unable to see things that are more or less far. In addition that I'm feeling some kind of pain around my whole eye: around my right cheekbones, in my right side of my face and sometimes all over the right side of my skull. I also noticed the presence of a liquid under my eyelid which I find it to be heavy. Additional facts : I use screens and computers a lot at night or during the day. I don't sleep during nights I usually stay awake for more than 15 hours. Thank you in advance.
