[SOLVED] Gave my home page the wrong name and now the site isn't working

I have wordpress installed in the root directory drkatiegriffin.com. I set my home page to be a static page. But then I stupidly named it welcome. So now instead of wordpress thinking drkatiegriffin.com is the home page it thinks drkatiegriffin.com/welcome is the home page. So if I look at the page source for any of the wordpress pages it refers to all the wordpress stuff as being in drkatiegriffin.com/welcome/..... and of course the stuff isn't in there because it's in the root directory which is where it would have looked if I hadn't named the home page 'welcome' but left it null.

And now I can't get into wp-admin to change it because wp-admin is in the root, but now wordpress is looking for it in drkatiegriffin.com/welcome/wp-admin.....

Is there somewhere I can fix this in the code and then have access to wp-admin again so I can rename it to nothing (null)?
