Okay, so I might be freaking out

It started on Friday. I had this really weird headache (I never get headaches). Had one on Saturday as well. And then on Sunday, I tried to focus on my hand (my hand was close to my face, but not too close.) and I got a shooting sharp pain in my right eye. So this morning I had a slight headache, but nothing major. But then just now I got this terrible headache. And then I got this black line on my vision. I still have the headache and the black line I think is starting to fade away, but I'm kinda freaking out. My mum is going to schedule a eye appointment for me. 

Aw, that’s no fun!  Hopefully it’s nothing serious! :(
