Can I get a vacation from anxiety, please?

Leaving next Thursday for a long weekend stay on the coast.  I wish I could say I'm excited about it but all I really feel is fearful anticipation of what *might* go wrong on this vacation.  I might freak out during the 3-hour drive, I might have serious anxiety, to the point of panic, the whole time because I won't be in my "safe place".  I might end up ruining the vacation for my whole family because I just won't feel good while we're there.  It's all so frustrating.

I tried to get an appointment with a new dr. before vacation but she is at a conference until after my trip, so I guess I will see her then.  I was really hoping to speak with her about getting a prescription for klonipin.  SSRI's have not worked for me and the beta-blocker I am trying now just makes my heart hurt a lot and causes me more anxiety.

I haven't had a panic attack in over a month, which is awesome, but I feel like my overall anxiety level is getting higher and higher.  I also haven't needed to take any ativan in over a month as well, which I am also very happy about.  So why do I still feel so crappy!?!?  I feel nauseated with anxiety all day long, and not rested at all after 8 hours of sleep.
