Hello Sir, Im 13 Years Old And Im Scared About

Hello sir, Im 13 years old and im scared about the fact that i think i have an eye infection.

My left eye keeps hurting all the time.
It feels like a sharp pain and you can't do anything than cry and scream.

When my eye starts hurting i usually get dizzy, and somethimes i even throw up.

Everytime i think about the pain in my eye it somethimes starts hurting.

I've noticed that my vision has become worse over the past 2 years.

The pain in my eye comes about every 2-1 months.

The pain in my eye came around when i was 6.

I also remember that i got hit by a baseball bat, since then this sharp pain has been coming into my eye. Im not sure if this was the reason of it or not but it might be, i had a brown cirkle arond my eye and i was bleeding by the skin around my eye, the baseball bat didnt really hit the eye but whats around it.

Im scared and dont know what to do.
