How to say "good night" in Korean language?

I am bored.. Nowadays, my daily routine is killing me. I really wanna explore the other side of the world but the plane ticket is killing me even more. I hope I can visit Korea. Dang! It's really my dream. I'm getting crazy.. Nothing, just I wanna express what I feel inside now. I can't post this to my facebook account since that I do have lot of friends there. I'm afraid they will think of me that I am crazy...

I feel like I am an outcast today.. I don't know but it's really strange when few of your friends will suddenly stop talking when you're about to approach to them. It feels like I'm an outcast, that they don't want me to join them and that they want me to just be alone with myself in the corner.
