I need sleep

Yep, I'm utterly exhausted. I did the whole four corners of Joburg thing with my brother today and when we finally got home I was convinced I would have a bath, crawl into bed and go to sleep. But after lying in bed in the dark for what seems like hours I'm still awake, yes it's still relatively early but when you've been awake since 3am and haven't slept more than maybe 6 hours since Friday it really is time to sleep. I hate being this tired because it makes me needy and emotional. I haven't cried yet but the tears aren't far off and I need to be held but since thats not happening it just perpetuates the desire to cry, which of course leaves me needing to be held even more and so the circle goes, visciously. Time to find a really boring movie and bore myself to sleep me thinks. Gotta get some sleep before Wednesday;P
