The language barrier is frustrating, but not impermeable!

I guess I will say that I have had too many experiences about the culture navigation here that I will sum it up into one sentence: Even after a year of taking a Korean Language class, I am still VERY insecure of speaking or using the language around native Korean people. While being in Korea, I have felt not only overwhelming care, but also that I am the most annoying person on the planet. I know, very contradicting. But I feel like a bother just because I know a lot of the words that are being said both to me and around me, and I want so badly to be able to express the many feelings that I have about what's being said articulately to the Korean people around me. The language barrier is so frustrating for me...I just want them to know that I am smarter than I appear, I guess? I hate knowing that I am (sometimes) being judged as another ignorant foreigner. I want them to know my skills and my appreciation that I have for the people and their culture. I want to express that, but I can't. And sometimes, I feel very isolated because of that. HOWEVER, this only means that in my continuing years of enduring Korean language classes that I will try harder to improve not only my comprehension, but also my speaking abilities! SO BRING IT ON, INTEGRATED KOREAN II.
