Hi there flabtofit - just read some of your diary, I think you are doing really well!
Although my son is now 12, I remember very well those first few years, when I had to battle with the guilt of working full-time, the broken nights making me feel like rubbish and the lack of confidence that came from putting on loads of weight. As a senior manager, I also had to deal with people at work no longer taking me seriously - it was almost as if once I'd had a baby, my career was over and I was seen to be just going through the motions at work - so untrue, but it really damaged my confidence.
So don't beat yourself up for getting stressed out and fighting the urge to turn to comfort food... just remember you are the one who is in control. I ended up adopting an 'I'll bloody well show you!' attitude, felt like I was putting on a suit of armour in the morning, so that anyone's comments or looks just deflected off the armour and didn't bother me one bit, while inside the armour I was reinventing myself as a slim, confident mum who was bloody good at her job!
It worked and I lost 3.5 stone. Put it all back on and more when I had health problems and my marriage broke up three and a half years ago - but I'm here again and not about to give up anytime soon! Godd luck x
