I have no problem leaving my house to go for a walk or just to do some errands around town or something, but it's more when I'm leaving town.  Basically, I get really anxious any time I have to leave town for something the next day and I almost always end up having a horrible night.  I just can't stop thinking about planning out every step of my day and cycling through it over and over again in my head.

The silly thing is it's sooo much better if it's just spontaneous and I leave for something the same day (can't have a bad night if you don't need to sleep, right?)

Part of it is driving.  I'm definitely less anxious if I know I'm getting a ride instead.  I actually enjoy driving, but I get anxious about it nonetheless.

Does anyone here experience anything similar?  How have you dealt with it?
