self consciousness

So yesterday was my niece's 15th birthday. Prior to her big day, I had to go shopping for a nice dress. The store had one dress in the color I wanted. The size was six sizes smaller than I was before starting this journey. The dress was form fitting with one inch straps at the top. I absolutely could not wear the dress as is. I had to buy a little black jacket to cover my arms. They are so big still. The dress really showed my curves, something I am totally not used to seeing. People told me how good I looked, but I just couldn't get over how I felt inside. Do you ever try on clothes and see yourself as the bigger size still? I think this is what happened. Although I am smaller, I still visioned my self bigger. There were moments were I just could not get over thinking "how big is my behind still? why haven't the arms gone down more? when is the tummy going away? I was my worst critic and being self conscious did not help. Why is it that I could not be comfortable in my new attire? I know I need to concentrate and see myself as how I will look when I reach my goal. It is just hard when reality stares you right in the face.
