I need advice.

Folks, I have a dilemma... a very serious dilemma. I came to Korea seeking an adventure of a lifetime and a new experience. For the most part, the country has fulfilled every expectation and more. The culture and food have been absolutely amazing. The people have been gracious and exceedingly helpful... Well, that's not entirely true. Most of the people I've encountered outside of work fulfill this description. At work, I keep running into the metaphorical brick wall that just won't budge. The complete lack of communication, major inconsistencies, and overall failure of logic within my school are literally driving me crazy. Most people tend to describe me as a fairly patient person. Well, my patience is very close to wearing thin. As a matter of fact, it is already wearing thin and the ice is about to crack. (The 'ice' is in reference to my sanity.) For the most part, my time actually spent teaching the students is fantastic. However, they are even starting to push my buttons and test my limits. It is the end of the semester for them. Kids will be kids, I suppose. As for the aforementioned issues (communication, etc...), I've repeatedly tried to address them with the powers that be and have only been repeatedly met with that same brick wall. The lack of communication is becoming an almost daily issue and is starting to infringe on my ability to perform my job. Their solution: there is no need for one because they see no problem. Ugh!

I spend a third of my day at work, a third of my day sleeping, and a third of my time trying to find a distraction from work. Outside of school, I love pottering about the city and meandering my way around the country. I've met several great people, including two people I'll probably be friends with the rest of my life. If it wasn't for them, I'd already be sleeping in my bed back in Texas.

The point I'm trying to get at... I'm really not happy here. I'm not a quitter, but my work situation is borderline unbearable. Basically, I spend a third of my day being miserable. 

I need some advice, words of wisdom or support, anything...
