['I am feeling nervous about leaving for my trip. I am supposed to go for three months.', 'That sounds exciting and a little scary. Where are you going?', 'I am going all over western Europe. Its a little daunting to think about.']
I took a trip to europe once.  Once you get used to riding the rails and traveling around it's a blast.
I am supposed to leave for a three month backpacking trip. I am feeling a little nervous about going though.
