Anxiety is not a weakness. It is an infinite repetition of possible events.
Your mind goes through dozens of possibilities for what could go wrong tomorrow. Not because something is wrong with you, but because some part of you is trying to protect you from possible pain, disappointment and the unknown.
The problem is not that you are anxious. The problem begins when you start believing every picture your imagination paints, accepting it as an inevitable reality.
Most of the scary scenarios an anxious mind creates never become reality. These are only assumptions and not predictions for the future. And you don't have to live through events in your head that haven't even happened yet.
stop. Take a deep breath and ask yourself: what is happening to me now? Not what can happen tomorrow, not what remains in the past, but what is in this very moment.
