Really great writing, Mohammed. We, indeed, are our biggest enemies. In those lonely hours of the night, when fearful thoughts sneak into your mind, they can have tremendous power over you if you don't learn how to control them.
I've taught myself an efficient method to completely shut down my mind from these thoughts. What I cannot fix at that moment, I can try to solve the following day. What I cannot change, I try to find a way to achieve peace and acceptance.
There will always be another thing around the corner scaring you off. You must train your mind to handle your emotions, set your fear aside, and find peace at the moment.
