Hey aryeh,
I read through your thread today and want to congratulate you for being such a warrior in the face of strong enemies. A wimp like me wouldn't last a day in secular college, which is your place of combat I assume, and it's just amazing how you're going on such a long streak despite that environment. And listen, pal, everyone has days where they feel "dazed and confused, cut off from the world, undeserving of kindess from people or G-d." That's where KOT comes in.
Sometimes people get in these moods, funks if you will. But that's all they are. Moods. Funks. When you're in these moods you can't see the end, everything looks hopeless. Just like the way I felt yesterday in the afternoon. I felt that I couldn't defeat the yetzer hara. But then I called a friend to pull me out of the swamp I fell into, and he helped me out. Keep on posting, and we'll help you get out of funks fast. But sometimes they can be persistent and you just need to truck it through.
As for the music issue, try replacing it with good stuff. Chopin is good. Rachmaninov too.
