I hope your t texts you back. I figured my t would barely know what a mobile phone is but she has a blackberry and according to her she's actually a good texter so you never know! Can you curl up under your duvet and watch something you enjoy and try and get some rest. I keep hearing that resting with your eyes closed is nearly as good as sleeping - don't think that's true but it might help you feel a little better. Keep writing here if it helps. I'll be here on and off most of the day. Hang in there.
