Hhi

I am due to leave for Cornwall in around 3 hours and i am seriously freaking out..its a 6 hours drive from here and i am not a good traveller at the best of times. I am so worried about being away from home, worried i will freak out and lose it when i am away from home..i am getting myself in a real state..i thinking about cancelling the trip :-(..trouble is i am due to attend my best friends wedding whilst i am there, instead of looking at this as a happy event i am terrified and feel trapped by it..if that makes sense...help, any advice?
