Frustrations

For some reason I sit in my apartment everyday, surrounded by the silent mystery of no people. And I do nothing, you'd think the quiet would be a great atmosphere to get homework done in, and for some people it might. But lately for some reason that I don't understand I've been listless, focusless, and most importantly feeling rather alone. This I don't understand, I have friends at school, I have wonderful roommates who are a blast, I'm finally starting to get in shape, I have amazing classes, with great teachers, and even with all that I feel isolated. It just doesn't make sense. There are times when I sit on my couch staring at my computer trying to convince myself that homework is what needs to get done, and the next thing I know I'm on Facebook, or youtube, or Hulu, and once again procrastinating everything that needs to get done. 
Of course I can't tell my mother this because then she'll worry about me more than she already does, which she doesn't need, she has enough stress in her life right now, with work, my dad, and my sister (who is simply insanely busy). And so I bottle it up, and the desire to cry tickles the corners of my eyes, while I sit stoically alone in the shadows of my misery that I have created on my own. 
I just hope that soon this will go away again... maybe I'll need to go see the counselor again, not that that would be a bad thing, I just want it all to go away so that I can be a normal healthy person who doesn't have emotional imbalances.
