The Anxiety of Boredom

Who would have thought that boredom would make one anxious? I mean, I'm going out of my skull here twiddling my thumbs. I'm distracted and restless. I know, I know... go to the gym (not likely), go for a run, Lord! Go to Salsa or SOMETHING! ANYTHING! Quick a distraction! I feel like I"m just biding my time waiting for this restlessness to pass. I guess it was something that has characterised most of my teenage life - you know, got bored, got anxious, ate food, got fat, escaped into televisual um, escapism... but now I can't do that because I've given up sugar (no more stuffing face) and films (no more escapism) so the problem that always was there has just reared its head again. Need to find constructive way have outlet.

Any suggestions? Becuase I'm not sure how long I can practice breathing in and then purring out...
