Oh hun, sorry that you feel so terrible. You really need to try to take a step back from this and get perspective on what you have acheived and your own sense of body image. To view yourself as a size/ shape differnt to what you are is not uncommon, but at the same time can also be a key feature of eating disorders. Whilst I'm not suggesting this is the case, you may just be having a bad day, you do need to try to give it some thought. At our weight and height i should imagine you do look good!
Our body image perception can often be affected by other areas in our lives, often a persons sense of self esteem and self worth are major factors. Is this really about your body or just not feeling happy in yourself? Are there other areas of your life that you are unhappy in, and you find it easier to focus on the weight, as this is seen as more 'controllable'.
Look, I'm sorry for the waffle. You came here asking for help as your weight wasn't budging at you've probably not recieved the help you hoped for. Just worried about you hun and hope you are ok. You know we are all here for you to talk but maybe it may be useful if there is someone close to you to really talk about how you are feeling, or consider seeking help from GP/professionals. All the best xx
