I just think if she has lied about anything in her whole 'journey' then eventually it will all come out. You'll always get caught out on lies. Might take hours, days, weeks, months etc but a liar will always get caught.
If it was me personally I'd be like ya I got surgery but I'm going to SW to build a better relationship with food and keep myself accountable. I'd be telling everyone I got surgeries done sure loads of people in clonmel have had surgery done. Its really not a big deal. Theres another girl from clonmel sharing her weight loss journey. She got a TT late last year and puts up pics of her healing process etc. Fair play to her. No BS, no looking for attention. What you do with your own money is your own business. If slimming world was really that effective we would all be walking around with skinny bodies
