My T has said that the overthinking and over analyzing is a way for me to try and collect as much information about the situation as I can, because in my case knowledge = less anxiety. If I go in knowing exactly what we're going to talk about and how we're going to say it, I'm not so anxious. There's no "what if's" or self doubts etc. This isn't possible most of the time though, so I'm learning how to reduce anxiety between appts and not overthink things so much- Writing has helped!

Also a lot of the sites n stuff on anxiety don't mention the finer details of it. Some people never have anxiety attacks, but instead go through day to day with a constant state of mild anxiety (or more), and some situations trigger an increase in physical symptoms- but not a full blown attack. That's me, but I still have anxiety even without the 'anxiety attacks'.
