No visual view/ code view only

Help, I’m a noob and I’ve screwed up already. I can’t get anything but code view on the text window. I click on visual and although the button is “pressed,” nothing happens. How do I fix?
(FWIW, I’ve been entering text by composing in Word–sorry, but I’ve been using it for ten-plus years and the composing windo on WP is so small–and the cleaning it through NotePad and cut-and-pasting it into the text window. Could this have messed anything up? Is there a better way to compose in Word and post on WP? My website is my screen name plus the usual extension.
