7 days to go- Insomnia

I really should be asleep. Almost 2 am but i just cannot stop thinking. My brain is full of things and its just keeping me awake all night. I will leave in 3 days and right now there are too many things to worry about. Work - what i need to finish before i leave, good bye's - who i still need to see/talk to before I go. My bagpack - is it big enough? its almost 10kg. a lot heavier than originally planned- will my back be ok?  my to do list - what else should i buy, what else should i read. The weather - is it gonna be hot/ cold , hope it wont rain all the times.Fear of what if i cant do it, fear of whats gonna happen. Excitment of whats ahead of me. Whats gonna happen when i do it?Happiness that Im leaving- sadness that i be away for so long alone. So many mixed emotions and my brain just feel like a non stop train which i cant stop. i watched " The Way" with Martin Sheen last night. Its about the El Camino. it made me cry, laugh & think ( kind if what Im expecting from this trip anyway). on the one hand i just want it to be over and i just want it to be June. so i know that i had done it and i can share my journey with all my friends and family on the other hand i want to experience all of it now! im excited who will i meet and learn other stories of why people choose to walk the Camino. everyone wished me to find what im looking for and some answers but im scared. what if i do? what if i dont? what if the road will change me too much? what if it wont change me at all? i wish someone could answer all my questions...i am so tired. still i cannot stop thinking "what if".
