Moody... Hormones???

This past Sunday, I hosted a family gathering for my husbands side of the family and had little problems. I don't get along with his mother and there was little conversation with her. I had very little drama at all at the party. 
So why do I feel like I hate all of them!? Is it the hormones? 
I'm 35 weeks pregnant and I don't eat red meat and I got so pissed off (after they all left) that someone put bacon in the potato salad and got me to eat it. Logically, of course they did, but in my head I feel like growing up. 
My mother-in-law brought me baby medicine... Why does it make me so angry? 
I feel like crying and I'm so pissed off over REALLY little and illogical things! Does anyone else feel this way?
On top of all of that, I'm not even a little bit excited about this baby coming (a fairly new thing)  and it's all because I have to deal with family at the hospital... Not the whole pushing a baby out of my vagina but because I don't want any family passing her around holding her. I know I'm crazy, but please tell me I'm not the only one.
