Hey Cass I had it 3 years ago, long before my diagnosis and after 15 years of dieting and having not much luck it took me a year to actually physically see and accept that it had worked. I think it was due to the fact that I wasn't physically needing to work out and diet to achieve the goal. Its very normal to not see the changes. Also Remember that often size and shape can transform even when your body goes through a 'stall' and stops loosing weight, which is bound to happen so sometimes paying attention to how clothes fit is a better indication than the scales and allows your brain time to catch up.
