What am I learning?

So what I repeatedly heard from people encouraging me to go on this trip was, "It'll be life changing! You'll learn so much about yourself!" So what have I learned about myself? Well, so far, I know that I need a lot of time to myself. Why? Because after so long, I want to strangle people. I'm frustrated with myself though, and I wonder why I get so frustrated with people? I try and make excuses like, "Well, they are a lot younger than you are, you are at a different frame of mind," Well, maybe so, but I'm afraid that's just the excuse I make for myself. I have friends here, but I can only take them for so long before they start waining pretty thin on me. I've asked myself, "Is this normal for me?" Well, it's hard to say. There are 9 people that I am spending the majority of my time here with. I suppose it's logical that I would get really sick of them. However, I spend a lot of my time with the same people while I'm at home. On the other hand, I suppose I pick that lot of people myself. I know most logical leap would be that I should start trying to make friends outside of the group. Well, right now, that's looking like a pretty big leap. I don't have a lot of confidence in speaking German, and top that onto your normal lack of confidence and it does seem a bit more overwhelming. Well, yes, that's where the learning is supposed to come in. That's where you are just supposed to grow a pair and make some changes. Well, we'll see. But damn it, sometimes I feel like busting some ass and taking some names...
