I am an angry individual

So... Yost and I took two days off of work. Doesn't sound like much, but for us, that's amazing. Yesterday, we went to the zoo, Buffalo River State Park, Olive Garden, and to watch Nacho Libre. Tons of fun. Today, we went to Grand Forks to go to their state park and the mall that we were told was amazing (I wasn't much impressed...but spent $ anyway)... We cut it short so that I could go to knitting night tonight. Got home early enough to take a nap. Woke up and I was already five minutes late. Rushed out and started driving with the directions I was given (I've never been to this chick's house before). Let's just say that almost an hour later (and one long crying fit in the Wal-Mart parking lot later) I was back at home with an angry spirit. Why in the hell??? I'm very upset right now. Don't know what to do. I don't think I'll ever try to drive somewhere new again. It's not worth the frustration. I feel much like cussing right now, but I'll try to keep it at a minimum. I had three people outside my husband to wish me happy anniversary and I think Yost was very upset that none of his family called him the day of or the day after. Poor guy. I still love him though. He puts up with a lot of my...everything. Sometimes I wonder if I'm bipolar or clinically depressed or something or if I just have a major hormonal imbalance. How can I be so happy just an hour ago and suddenly there's a massive change of wind? I'm hot.
