Help me get through this nightmare

I have a tumor of the pituitary gland.  Its 2 inches big and is at the moment making me almost blind from my left eye.  My insurance won't cover the entire cost and I'll have other doctor visits after the surgery.  I never thought I'd be in this situation but Im hoping for the best and so is my family and friends.  Please help me through this I will be infinitely grateful.

-Thank you
