stop questioning everything

It has come to my attention that I have a tendency to question every decision and aspect of my life, and I am starting to realize this maybe why I am so unhappy and stressed all the time. I have never been one to make new year resolution but this year I decided that I need to change a lot in my life and I need to just be happy with myself. It's been 7 days and in starting this effort to find happiness I have been reviewing the way I think and live. I have come to the conclusion that I need to realize that even though I have made tons of mistakes that I have also accomplished a lot too and I need to trust that not every decision I make is going to be the wrong one. I am so afraid that I am destined to screw everything up that I stress over simple stupid things in my life. When coming to realize this I started wondering how many other people have the same fears that I do, and I wonder how many others question their ability to overcome obstacles and bad luck that cross into their paths. Sometimes I feel as though I don't deserve to have a simple life every time things seem to go well it doesn't pour a hurricane hits, and even though I have yet to give up and I don't ever plan too! I have gotten to the point that no choice made in my life is simple. I stress over the stupidest things and tonite or I guess this morning I vow to myself that I will change this!
