You have had a hard journey but it will be worth it. You are only 25, at 25 I was heavy and had no health problems other than weight. My doctor warned me year after year that I WOULD GET DIABETES....i didn't believe it, it wansn't in my family. Well the Dr was right and I tell you that was such a blow to me....unexceptable that I was told for all those years and paid no attention. It is a devistating feeling to know you caused yourself all the problems related to this disease. It took years but it happened to me.
STICK WITH IT, you will get pregnant as the weight comes off and you will want to be healthy for those kids.
My 21 year old broke down and cried when I told her I was having the surgery, I had no idea how much my weight and health hurt her....cries of happiness that I was going to be here for her.
You are doing great, keep it up, it is worth it!
