stuck zoomed in

ok please don't do anything to this blog. I'm completely out of luck, I've tried everywhere and there doesn't seem to be a solution. i reset minecraft, do everything everyone has said, but I seem to be stuck in some sort of zoom in. sort of like optifine's zoom in, but i'm in vanilla minecraft. no clue how i did it, but it seems to be stuck, no matter what server, or if i'm in single player it's all the same. just to be curious I went to optifine and hit ctrl, but it zoomed in even farther. if anyone knows whats going on, or how to fix it PLEASE help me.
thank you.
