Where Are All My Posts?

Where did the last 3 months worth of post go to? The last one that is showing up is the one I posted on May 29th! I am so aggravated about this. Why don't they show up? Where did they go? And why did this suddenly happen? I am not tech savvy, so I need to find someone who is. Because I know that my posts were there yesterday. My mom was reading through last weeks, while we talked on the phone. Come back posts...where ever you are!
