I'm so confused

I apologize for the blog lately - something really strange is going on, and I don't know how to fix it. Several times over the last few days, for no reason at all, my blog has reverted back to really old entries from November, and I don't know why. It's really really frustrating, and I have no idea how to fix it.

Bear with me while I try to figure this out...and if anyone has a clue why this is happening, it would really be helpful to me!
