Hey :-)
I am only new here too but have always been bigger as long as i can remember (i'm 18). I struggle with will power too but after having found this site and looking at all the amazing progress pics and advice, i feel i can now seriously give this weight loss a go and succeed this time! When i feel my willpower slipping, i find looking at what people have achieved here makes me think..'well i'd rather look like that than eat a piece of cake!'.
I know it's not really advice, but there are other people in similar situations and i've already found 3fc to be an amazingly supportive and helpful community!
So good luck on your weight loss and hope you meet loads of helpful and supportive people here!
