Whatever your fears trust me being overweight is a LOT more scary. Not just diabetes and heart disease, but cancer and dementia are linked to it as well. Plus your everyday life is so much harder. Moving, breathing, just being is harder.
You will find when you loose weight not only your body changes, but your mind clears up, your energy goes way, your moods go way up, clarity goes up. You will not believe how much better life is.
Your quality of life goes up so much. Sure it will be unexplored territory how others view and treat you. I am a guy but with me it has been nothing but positive. Dozens of co-workers and friends saying how great I look and how proud of me they are.
Whatever 'difficulties' might come from losing weight, they are not even close to the real, every day, even every moment difficulties of being overweight.
