Excitingly terrified

So, I'm realizing more and more that I'm terrified of all the exciting stuff coming up. Excited, but terrified.
We leave tomorrow to Houston for 3 days to find a house. In essence, we have two days- two whole days to find our first home, where we'll start raising a family. In a state we've only visited once. We're SO excited, but I'm feeling the pressure a bit too. We've just about lost patience with our current apartment, and as the winter comes I'm excited to escape the cold as much as possible. Lucy is excited to have a yard of her own so she never has to sit in her kennel for 9 hours again.
A lot of the homes we've been looking at online are great. Mostly 4 bedroom, 2 story, built in the last 5 years... for 120-140k!
Which raises the next thing I'm afraid of. We're using my stock options to help come up with money for the down payment. I vested (my options became available to me) on November 6th- the day the stock market took a turn for the worst. And, unfortunately, a 1% change in the market comes out to a 5 or 10% change in my company stock... and it went from 36 to 26 in about a week. It's gone back up a little, and it may go up more between now and Dec 15th when I go into a company blackout period (to prevent insider trading), but... I feel so unlucky! Had I vested and exercised my options just one day sooner... we'd have probably 6k more to work with! At the same time, I feel so blessed just to have the options and with how the timing worked out. Pray for the stock market for me (ironically, it's down because of the low housing problems right now).
I think my other big fear/excitement surrounds the baby, or rather, parenthood. Obviously, I'm thrilled we're having a baby. This has been the biggest thing for me to look forward to over the years. But yeah, it is a little scary. Aside from the fears about if the baby is healthy, if I can make it through labor, if I can keep a baby alive... the big picture of being a parent is so big I can't wrap my head around it. And the fact that Kenny and I both grew up seeing very different parenting styles (heck, between my two parents I saw totally opposite parenting styles) makes me curious to see how this will work out. I have no doubt he will be an amazing father.
So please, share in our excitement, but pray that we'll be able to make a good choice this weekend, and tackle everything coming up:)
