I didn't understand the whole story either but it doesn't matter

You have anxiety about getting anxiety again. Pretty simple and really common. That is probably what I suffered from the longest

Understanding what anxiety is and how it affects you is what cleared it up for me. I had always fought it but once me and Anxiety started to get to know each other better,, he was much less scary

Once I could decipher between my true thoughts and my anxious thoughts, it was easy to dismiss tha anxious ones
