sarochka - it's taken 18 months, so steady and sensible I hope.
I wasn't always big - I put the 8 stone on in 4 years - long story involving a very very difficult bereavement and 2 pregnancies. I stopped looking after myself and ate rubbish. The weight piled on alarmingly. I didn't have the will to do anything about it for quite a while, I was so upset at what had happened.
Then there came a point where I knew I had to stop the rot - my weight was completely out of control and affecting my health significantly. I honestly didn't know if I could stick it out - it felt like such a mountain to climb, I know I avoided the issue for a while because I thought I was a lost cause . But then, I realised this wasn't an insoluble problem, just one that would take some time to tackle.
I knew it would take a while and decided that 7lbs at a time and about 2 years out of my life, was a good investment in my long term health. I also have tried to be realistic - there are times where I've been away for a weekend/hols and put on 5lbs, but immediately got back on the scales, told myself I had a nice time and then got back on track.
Taking a long term view has really, really helped, but hey it took 4 years to put on 8 stone, but only 18 months to get the majority off, so not that long really.
I had a lot of back/joint problems because of the excess weight and just couldn't cope with any focused exercise programme for a while because of it. So, focused on rethinking my eating at first and only in the last 4 months have I gone into a gym, which is really helping with regaining fitness and some muscle tone!
I understand when you say you feel down - it got me down for a long time. I learnt to be patient with myself - any loss must be celebrated, any "staying the same" means I am still in control of what I am eating, and any weight gain is not the end of the world, but a chance to review what happened that week and start the follwing week afresh but not give up.
