hi sarah! - i am holly.. i know how it feels to lose 8 stone and then put a big chunk of it back on - i have done that about 5 times in my life - its heart breaking and yet i still have never been able to maintain my goal weight - good luck with slimming world - i used to that and i found it enjoyable although i do calorie counting again now as i always end up going back to that - i wish you the best of luck on your weight loss journey! xxx
