I feel like a monster

Omg!  I feel like an insane monster.  I seriously feel so annoyed at people 24/7.  I was never like this before I am 8 weeks and I feel like I could chew people's heads off.  This just started the past week or so.  Doesn't help that I am insanely exhausted, naseaus and gagging all day either.  Will this last the whole pregnancy?  Is anyone else feel like this?  I was so joyful the first few weeks now not so much.  I'm so excited to be pregnant and have this baby but these hormones are making me nuts!
