I was googling why I "pace uncontrollably" and came across this forum.
I pace while listening to music in a track around my room, and I usually can't stop even if I hit a wall or something. It drives my family crazy, but I love music and my mind is always somewhere else when I do it, I can stop myself from hitting things when I'm paying attention but I feel really uncomfortable when I try to stop myself.
It doesn't happen if I'm on the computer and typing or writing and not really listening to the music, or if I'm in a room with someone else and I force myself to sit down.
I'm just a little worried because I'll be in college in a month and I'll have a roommate.
