3 days!! I am a bakset case!

I did my last run before my half marathon. I ran 5 miles and ran pretty good, just under 9 min pace.
I am becoming a basket case! I am worrying about everything now. Getting there, parking, getting to the expo, dinner, what am I going to wear, you name it I am worrying about it. A friend told me that is normal!
I got a massage on Monday. I haven't had one in a long time, it was nice. I have missed that.
I am so tired tonight. I know I need to get alot of sleep the next 2 nights because Saturday night I will probably not sleep much.
I know I am trained and ready now all I have to do is go out there and do it!!
