I've Keep My Contacts In To Long They Are Only

I've keep my contacts in to long they are only for 2weeks then replace. I've keep them in for 2months. My right eye was burning and felt scratchy. Took it out and removing it caused server pain couldn't open my eye (lots of pain) flushed my eye out,didn't help. Pulled my eye open and have a blue line on the white part before your eye color. Now lots of pain in the complete back of my eye. Hurts to close my eye. Now can't see cause my eye site is poor. Headaches for trying to see (straining) what do you think and what should I do? ER?
