Shock Waves (nourishment is important)

Stacey’s having me read a number of books, which is actually rather helpful. =) One highlights the symptoms of culture shock.
The funny thing is, I remember taking notes from my Living in Another Culture class that I took 2 years ago, and it must have been the same content exactly. But then it was so sterile- just simply words that my dear professor was explaining.
Now to be in it. I see the difference in learning something theoretically verses going through the very steps yourself. goodness. I was reading it Tuesday night, and was like - this is why I am feeling this way! This means I'm not the only one! This means I'm Normal! Anyway, but I wanted to share it, so maybe others would understand what it's been like a little to be in a new culture. Whether or not we even realize it, when we grow up in a place, we learn all these clues and rules about how to interact with people, how to operate, but it's all done silently, so a lot of times, you can't even fully articulate it... but when you go to a new culture, all the rules are different:
"These signs and clues include the thousand and one ways in which we orient ourselves to the situations of daily life: when to shake hands and what to say when we meet people, when and how to give tips, how to make purchases, when to accept and when to refuse invitations, when to take statements seriously and when not...
...being continually put into a position in which you are expected to function with maximum skill and speed but where the rules have not been adequately explained..." (... is REALLY hard!)
The book went on to describe the overall symptoms of culture shock:
anxiety
homesickness
boredom
depression
fatigue
confusion
self-doubt
feelings of inadequacy
unexplained fits of weeping
paranoia
physical ailments and psychosomatic illnesses. 
(in addition, signs of withdrawal symptoms or aggressive symptoms will also occur.)
I kind of hope that things will start evening out now, and I'll be starting to adjust. But I'm not sure how long it will take. I guess I'm also concerned about losing touch with friends back home, and the fear of being replaced is sometimes overwhelming.
Today when I had to find the bus stop and crossing the streets was fairly terrifying, I kept saying to myself, This is an Adventure. This is an Adventure. And somehow, that actually helped. I'm only going to be here for a year, so I don't want to be stuck too long in the down slope of culture shock. I have kind of already decided that I'm going to look back on this year and call it one of the best experiences of my life, because it's been so good to see another part of the world, to meet new people and take risks, and be stretched, and grow like a tall and healthy sunflower. =)
Lately, the tipping point(s) or most frustrating things for me have been that my Internet just stops working at about 10pm every evening (which would be prime time for talking with people back home...) The other thing is getting around without a car. and the third has been eating right (I had a bad experience with making an omelet and it not tasting like it should), and the fourth has been not hibernating in my room (which is so easy to do!) but spending time with people. The fifth is figuring out what people actually mean, reading cues and such and not feeling too out of place.
I think i'll go try to make some food now. =) Nourishment is important.
