Losing faith on yourself

One of the most terrible feeling in the world is probably when you lose the faith on yourself. It really is quite normal when you lose faith on someone else, on an idea, on an knowledge. But losing faith in yourself is like losing faith in everything in the world. When you lose faith in yourself, you don’t even believe your instincts, you don’t have the confidence in what you are doing, you have no certainty on how you are supposed to walk on the earth any further. It is not only walking without knowing where you are going, but more like walking while you are not sure whether you are supposed to be walking at all. 

When you lose faith on someone, there is big probability that someone is going to either convince you otherwise or tell you that yes, he was not someone you believed him to be. When you lose your faith in an idea, you automatically turn into another idea, into something contradictory. When you lose faith in yourself, who are you turning to? Will there be anyone who would try to convince you otherwise? Or well, would people even know at all? Would people even realize it? Would you?
