Dark night of the soul

Plagued by self-doubt, loss in self-confidence and unsure of what to do next...
I used to hear people go through all of the above (almost as a well laid out process) when they try to do something different from their regular life-path...
I dont know when these experiences will end: most likely it will be when I finally get onto the path I have chosen or I go back to the path I had deviated from...
The wait is painful, the mind is numb, the clouds are upon me....it's the dark night of my soul...
