You know the feeling when you feel like you're missing something?

I feel that all the time, I can be at my happiest, and still feel like something is missing or that something very bad is about to happen. I never show it or say it, I just learnt to push it down in the depths of my feelings that I zone out. Sometimes I'm forced to deal with it when I'm deep in meditation or something triggers the feeling during the day. "I'm missing something" 

I'm on a constant search of eternal happiness, this world we live in today, we all suffer from chronic dissatisfaction. We can have everything, and still be unhappy. I don't want everything, I want to find what it is that I feel that's missing. Whatever or whomever that may be. For all I know it could be a hunger for a different life in a different country or state. A craving for change...
