Booking a Flight

I'm currently online checking prices for flights to WA. We actually got some money back on taxes this year (thanks to the little boy) and we have decided we are going to visit my family. I'm super excited but kind of nervous. It's been 16 years since I have seen or spoken to most of them. They are, essentialy, strangers. I did not realize how nervous I was until I was trying to book our flights. It is making me physically sick. I feel nauses. I am on the verge of tears and my stomach hurts. I think it's also a little bit that I'm scared to take my kids on this big of a trip. And I have to be the responsible adult. I'm scared.
