My insecurities

Insecurities consume me every now in then, and they make me to feel like I am trapped inside of myself and that I am never going to be able to go to the next level. They make me feel that I am not worthy to do the things that God has called me to do. They make me ashamed of everything that God has created in me. Insecurities make me jealous of other people in their ministry, and makes me compare my ministry to theirs. Because of my insecurity this weekend I had a big fit with God, like a full out laying on the floor kicking and screaming fit. Insecurity has a way to get into my mind like a sickness and flow through my blood streams. It's like cancer, that keeps coming back, and every time it comes back it makes you weaker. But most of all my insecurities are telling God that he is really not able to do everything, and that I can't trust that he can use me a broken person. Why do we have insecurities?
