Why do we fear happiness?

So I haven't really accomplished much since my last entry. Sad, I know. I spent my weekend trying to get myself out of bed, and for some reason found it to be the hardest task for myself this weekend. This leads me to question my ability to overcome my internal battles to commit to my plans many times. Why is it that we fear the ability to be happy, to achieve the ultimate goal for ourselves? It's like we almost stop ourselves from being the person we want to be. We questions our motives and intents and wonder if this will even be worth my effort? My entire being knows that in the pit of my soul, I want no more than to be completely successfull and happy. Yet, I happen to find myself being my number 1 enemy. When I am weak, I need to find myself strong in HIM. How am I to find that strength though? How can I open my eyes to see the value I have? I am blindsided by the negative despite my every effort to remain positive and strong. On my own I can't do this.
