Emotion/Relationship Changes

I've turned into this extremely outspoken picky person and I'm curious if this will go away. 

I can't find any baby clothes I like, I don't like any of the names, I've hardly bought anything because I suddenly don't like anything that was on my list of things to buy. 

My neighbor is suddenly irritating me, we used to spend a few days together a week for our kids to play together and now she irritates me, her kids irritate me, when she talks about coming to the hospital and meeting our new one after she's born, I have no desire to spend time with her or invite them over to meet the new one. 

I seriously just want to sit in my house by myself and I want everyone to leave me alone because they're so irritating. It's driving my hubby crazy because I can't make plans because everyone irritates me so much and I have to admit it's getting a little crazy.  I've always been a more polite person and that's pretty much gone out the window. I'm definitely rude and I can't even stop it, I've pretty much had to just not talk most of the time because I usually end up offending someone. 

I keep my phone on silent so I can ignore people and I've caught myself rolling my eyes when family or friends call. 

Has anyone else's crazy mood swings or changes stuck after birth or gone back to normal?
