I want to pull my hair out!

My 4 year old is not whiney, she never has been. She never complains, sometimes she will cry a little but for the past 4 days she has been the whineist little stink EVER! I literally want to scream and pull my hair out! I have no idea why she is doing this now! I figured it would happen after her brother got here but NO she is stressing the only nerve I have left right now and it's killing me. I am to the point of tears because I am due any second. I have had primordial labor for over a week, lost my plug and feel like a ticking time bomb. To make things worse I constantly have family asking me how I am feeling or if I am still contracting. My husband keeps pushing me, constantly asking if I am in labor yet, or I need to tell our son to get out. I just about cry every time because believe me if I could make it happen I would. I have tried everything but this baby is comfy. I am not but he is! I want him out so bad I am depressed and to top it off my 4 year old has chosen now to be a stink?!?!?! Ugh!
