I went through your concerns and i can definitely understand whatever you are going through currently. I guess you would be aware of your BMI which is around 32.0 which is a matter of concern, and it is something which falls in the category of "bese". Considering your height and your weight, i feel whether any one else in your family (primarily parents) are similar in being relatively short and obese
. If that is the case then it may be to do more with the genetics or the hereditary component which may be not so easy to get it addressed in a short time. Otherwise, by having less fat and carbohydrates in your diet and a average work up everyday would take care of the rest. Take care that you do not binge upon the food, if that is the major concern then consult a Psychiatrist
because there are pills which reduces the binge behavior. Always keep small targets while reducing the weight and each time you hit it, you are going to bounce back with more confidence and the best results. Right?
So Good luck.
