Hi Beth,
" Why does the anxiety just pop up". I know the feeling - in my case as soon as I have had a good day , anxiety seems to pop back. Like today I am going to see my psychologist and I noticed the whole night and early morning I feel anxious with new symptoms. So why does this anxiety pop up- could be biological or perhaps it could be that anxious people may never be able to get rid of the anxiety completely. We could successfully manage our symptoms but anxiety will probably always be part of us. So when it pops up - perhaps we could acknowledge that it is present and then let it go as best as we can and not be too hard on ourself that the anxiety is back. I wish I was at the stage you are in Beth, for me since I had started the program as I had to search out for anxious thoughts and panic situations, I think I have felt worse as my critical self is thinking that I am more panicky than I thought I was and I guess I have to challenge this thought. I think also that it goes to show that when you look for something, you will find it. And I also think that when everything seems to be going well, some part of our subconsious brain must say something like" Hey this is too good to be true, where are you anxiety and anxiety and panic just pop up" So you have nothing to worry Beth. Have a good day :)
