So I think I figured it out, I changed my theme a few das ago and I'm guessing it deleted my tracking code so google could no longer track my visitors. I've fixed it and now i'm just waiting to see if Google starts picking up visitors again.

Yikes! Hope you find out what happened quickly! Good luck :)

Are you regularly posting quality content? Has your ranking changed or dropped, and are up updating content. These type of questions need to be asked in order to find out why no one is visiting your site, where you had traffic before. I cannot see any other reason why visitors may have dropped.
Hope it picks up for you, regards, Lisa
