Anyone else have crazy emotions nearing the end of their preg?

I'm almost 36 weeks and I've been freaking out. I'm so emotional right now and I don't know what to do about it. I have an almost 3 year old son and I'm trying my best to spend as much time with him as I can before his sister arrives, but I have been really lacking on cleaning my house. It feels like a tornado went through my house and I can't seem to muster the energy to clean it because I also have a cold right now. I also have gestational diabetes and they just told me on Wednesday that they want to put me on insulin even though I have kept my blood sugar in pretty good control, even though I'm 36 weeks along. Gah sorry I'm just spinning in circles. You are so not alone. I was actually just wondering if there was a thing called pre-partem depression.
