Hi SJ, I've just said this on another post but I'll repeat it here too.
Losing weight is hard. VERY HARD. We all got fat somehow which is why you find us here on minimins. BUT . . . you have to be committed to losing weight not only with your head but your heart too.
If you only THINK you need to lose weight then you will always struggle. But if you get behind the idea BODY & SOUL then it will happen. Tough transition to make and I agree with Emmaline, it's all about mindset.
BUT .... Are you expecting too much? If you've lost a stone in 6 weeks that's pretty good. It took me 10 weeks to lose the same amount - I'm just aiming for a pound a week and know it's going to take me all year probably to get where I want to be.
I started out with 5+ st to lose, lost 2+ of it and stopped - 'cos I was bored with denying myself what I thought of as "nice food". All the food that got me fat! I managed to maintain though and I'm now back to lose the remaining 3 st. This time not just because I THINK I need to, but because I WANT TO. Don't ask me how I changed my mindset because I don't really know, it just suddenly clicked.
Go and sit down somewhere, in somewhere you like - the garden, a park, the beach, whatever - and make a list of all the reasons that you want to lose weight. This may sound hard but if you find that the reasons are all for other people then you may have a problem. You need to be doing it for YOURSELF.
Chin up hon - it is doable. Just look at all the inspiring stories on here of people who have lost massive amounts using SW.
