All these hormones!

Does anyone else feel like they're going crazy?! This is #3 for me and I feel like it's gotten worse each time. I'm so irritated by anything and everything, even the sound of someone breathing! I have absolutely no patience what so ever. I know it's normal. It just seems so much worse than with my first or second. I'm 29 weeks and just so ready. I don't know how I'm going to last all summer!
