Travel Anxiety.

Hay guys, I've been on Paxil for 6 months now and it really has done wonders. But tomorrow I travel to a different country for a vacation. I've been looking forward to it the last few days but now the night before the vacation I'm so anxious that it's starting to make me feel I don't want to go. I keep thinking of what if scenarios and stuff that could go wrong. I have benzos prescribed to me but I don't want to use them every day for 8 days while I'm there. I'm really scared that my anxiety will make this trip a living hell.
