I know what you mean @Somethingsnapped
I was 12 stone 10 and a size 14 / 16 on the bottom. Probably a 12 on top as I’m small chested.
I have a small frame but carrying a lot of fat.
I have lost two stone and am now down at 10 stone 7.
I am still wearing the same clothes.
But whereas I was probably bursting out the 14 before, they are now comfortable and in some cases, too big.
I think I was in denial about how big I was. Although “big” is probably the wrong word, as I do have a fairly small frame. Probably flabby is a better description. I had a spare tyre right round my middle. Huge arse. Arms and face very fat.
Now that the spare tyre has gone, I have a shape again.
I’ve lost 10centimetres from around my waist. But, unbelievably, I thought I had a small waist before! (Denial, and also just thought it was small because it was much smaller than my wide hips).
My waist was 31inches, hips 43.
Now my waist is just under 27inches, hips around 39.
I feel so much better. Sometimes I even feel slim even though I’m still a 14.
im now into healthy BMI range and don’t think I want to lose anymore (obviously I’d like to be slimmer but I don’t want to be on the jabs forever and also I don’t think it would be sustainable for me to lose more) but somebody took a photo of me the other day…..and I still looked fat 

And this is me now weighing LESS than I did before I had my kids.
So basically, I just can’t really trust my own perception of myself. It’s just so difficult to see myself clearly.
Also, although I weigh less than when I had kids I’m guessing my body shape is just different.
I still need to tone up etc and I will keep trying that and I’m overall very, very happy with the weight I’ve lost…but I do just feel that I can’t really see myself objectively.
