Totally unrelated, but I have been feeling this way too in terms of my fitness. About two months ago I started making an effort to get up and exercise every weekday. My wife has been doing it for over a year now and even she gets into these funks where she feels like no results are showing. I know that inside the changes are happening that will eventually impact the outside, but why can't it happen quicker or more dramatically? I am guessing the reality is our bodies couldn't handle it if the growth happened too quickly or too unnaturally. Perhaps it is true as well for you that your mind wouldn't be able to handle it if the growth or change happened too quickly. I can attest to the fact that you never know what life is going to throw at you and I need to do a better job of existing in the hear and now. I love the line from the Michael Jackson song "Heal the World"... "we stop existing and start living".
