I'm so sorry, it was an accident! We have a major problem with spam blogs (splogs) and there were about 40 splogs created in a row. Your blog was in the middle and it was closed in error. I've reopened it so you can get back in.
I can't help you with why it is gone. I did go double check and it really isn't there (sometimes people use a wrong address and only think their blog is missing). I do know they disappear it you haven't updated in in ages (over 3 months) but that's not the case for you. I'd suggest using the contact us button at the bottom of the page. Hopefull it can be straighten out quickly. This is a great site and I've found my blog to be personally useful for my weightloss.
