Well, there you go. Dont work towards an unrealistic goal. At least you realize it may not be possible now, rather than later. Just keep making healthy decision and if it happens, it happens. If not, well, you will still have a healthy body and that is the ultimate goal.
Just work on getting yourself to a point where you are satisfied when you look in the mirror. And dont be too hard on yourself. When you do look at yourself in the mirror look at the positives and the progress you have made, because in the end thats what is important.
