Formatting went haywire!

My website went crazy all of the sudden, and the formatting seems to be completely erased. I can’t get in to my admin page either to look for a solution.

I had tried to change the wordpress address right before. It was http://www.meredithbaldwin.com and I wanted it to reroute to a different page, instead of my about page. I had changed it to http://www.meredithbaldwin.com/page_18 which is a different tab of my portfolio.

I left the site address at http://www.meredithbaldwin.com after reading through a tutorial online.

Then I tried to view page and have only been able to get the unformatted results. I need to get back to my dashboard to try and change it but the site simply redirects me to the messed up page.

Help! Please! I’m really stressing out about this one.
