Dashboard issues!

 For the past few weeks I have been having problems with my blog dashboard. I sign in and often it says I am following no one and I can't see anyone's updates/posts on my reading list. Does anyone else have this issue? I feel bad because I want to look and comment on your lovely blog posts, but I'm often not able to because nothing shows up and it sometimes lasts for several hours at a time.
 This sooo annoys me!  Please forgive me if it seems like I post things and don't leave comments on your posts. This is not on purpose as I absolutely love reading/commenting on your blogs. :-)
Thank you for understanding!
