Who have I become?

Over the past couple of weeks I have noticed a "change" in myself. If I had to describe myself right now, it would be with a short-temper and a sharp-tongue. I don't necessarily like this "new me", the crabby (this is putting it nicely) version of Lauren. The weird thing is.....I can't seem to tame this new beast from within. I am having to literally bite my tongue to keep from unleashing my mouth. My courtesy filter is no longer existent....but I want it back.

The truth is I am freaking out that this new version is permanent. Someone please tell me this is normal in pregnancy....and my "filtered-self" will return in due time. I bet my husband would like that, too.
