-Leaving Carl for so long -the actual logistics of it since conference people haven't confirmed and I haven't seen Donna in Nicaragua for 5 years. -Pressure from uni - I've GOT to get all the info I need, cos it's not like I can pop back if I've forgotten anything. -Loneliness, malaria, heatstroke, altitude sickness, robbery, Montezuma's Revenge. -Language issues -What am I gonna do with the ferrets??? -The insurmountable list of stupid bureaucratic tasks that I need to do before I go -Total lack of confidence with my project in general
