blog disappeared

Hi there, I visited my blog last night to get some links to other sites and all was well. I visited my blog this morning to make a post and my blog is gone and it is replaced with my old index page relating to an old site I had. The index page had spam tampering so I fixed that and loaded the fixed version that now displays when loading my blog url (www.shinekelly.com). Why might this have happened and how can I remedy it!
