Pregnancy hormones

So my hormones are driving me crazy.  I have been so crazy emotional today.  Started off with the guys at jiffy lube being complete jerks to me.  I had a major baby brain moment and was really confused.  I got in my car and just lost it.  Took me a good 20 minutes to stop crying.  And then just now Molly came to sit next to me and put her paw on my arm and I just lost it.  I do feel a little sad but I have no idea why.  I hate feeling like this.  I hate crying.  Any time I start crying over the last couple months I get such a bad headache and I hate it.  Grrr!!!
