Is it me that feel dead inside or is the world dying?

I am 28 and when I compare myself and the way I felt 15 years ago it is like night and day, life used to be fuller and I used to have a special feeling that I can't explain, not exactly happiness, but it's much deeper than that, it is like the difference between a really big tasteless tomato on steroids and a small natural organic tomato with pure taste. It's like in the movie the matrix when Morpheus told Neo that he had this feeling and it was like splinter in his mind driving him mad something that he can't explain. Something is missing! Is it me perhaps because I am getting older? Some of you might think that I am just over stressing but I am sure that something is missing, maybe it is spiritual or mental and perhaps both, and honestly I will not be truly happy unless I get that feeling again, no amount of money or success can compare to it, it's deep and hard to explain I wish I can put it into words, it's like you have been locked in a lifeless, dark, place with no oxygen, no smell and suddenly you get out for the first time in years and breath and smell again, not to say that I am senseless I do feel but it's like someone locked my mind and spirit, to make me suffer without me noticing, I hope I can one day in life or the next figure this out.
