You can definitely manage this! December the 1st last year I was just under 13 stone, 4 months later I'm 9 stone 4 lb. And trust me, if I can do it ANYONE can do it!! I was one of these people that kept on putting off losing weight but with a little motivation, I'm finally getting skinner!
Best of luck hunny, I'll be sure to come back and check how you're getting on and offer as much support as I can. The good thing about this site is that we're all in this together (cheesy but true) hehe!
