WHY HAVE I DECIDED TO JOIN WW?? A bit about me

Well, after several unsuccessful attempts, I rejoined a class in September 2003 after my Mam died suddenly aged 52 in May that year.
I lost around a stone in weight due to stress without even trying and I was spured on to lose more weight when I started recieving loads of compliments. My starting weight then was 11st 5lbs (I WISH).
I loved the plan, stuck to it religiously and got to my goal weight of 10st 7lbs, six weeks later. But I got a taste of being slim and so I went on to lose more weight taking me down to 9st 13lbs. I can remember jumping up and down when I saw the 9s on those wonderful scales...I don't think I had EVER seen that figure!
But my dieting sucess was short lived, I met my boyfriend in April 2004. Old habits started creeping back into my way of life and that meant the pounds were piling back on. By the time I fell pregnant with my daughter in April 2005, I weighed a depressing 12st 7lbs. During my pregnancy I was conscious of healthy eating and only gained 2 stone, most of which would have been my baby as she weighed a staggering 9lbs 1oz!!
Six weeks after giving birth, I re-joined WW AGAIN weighing 13st 5lbs, BUT again like the several other attempts I FAILED. I just couldn't stick to it. I was depressed and wanted to lose weight, my body had dramatically changed since having a baby and I HATED it. So I started WW again but this time alone. I managed to get down to 12 stone, I felt great, much better about myself...but guess what...yes, it didnt last.
The weight was now piling on quicker than ever, photos from christmas 2007 were dreadful. I looked like a frumpy old fart!! Not a 24 year old woman. I thought my boyfriend must be embarrased to be seen with me, he wasnt, he loves me for me but wants me to be at a healthy weight and happy in myself.
We finally bought our own house after renting for 3 years, we couldnt wait to move and I couldnt wait to join WW again in our new area. That was 12th May 2008, I weighed a massive 15stone 8lbs...OMG the heaviest I had EVER been in my life!!!!! I started off determined, I did well then I don't know what happened.
So here I am again, going it alone..taking it one day at a time. My starting weight now is 15st 1lbs...my target weight is 10stone. I WILL SUCCEED!!!!
