I'm 21 weeks pregnant and haven't slept since Friday night. I have a 15 months old ds who is a poor sleeper so I get broken sleep on the good nights but the last 4 nights he's been ill and I've got no sleep at all. Tonight he's asleep and I can't. I think I've got myself into such a state of tiredness I can't let myself drop off. I've spent most of yesterday in tears and I don't know how I'm going to cope tomorrow as I'll be even worse. I don't know what I'm looking for here I suppose just someone to tell me it will all be okay! I had some really dark thoughts today which is so unlike me I'm a bit worried about myself to be honest.
