I recently posted something like this where I thought I was getting better yet, bam it's here again. My sister, who has anxiety yet is able to live her life, advised me that to think anxiety as a common cold. This is difficult for me to do sometimes, but she says that is how she copes with it. When there are days for her that are anxious, she accepts it as a day of anxiety, just like you would be sick from a cold. She always also tells me to listen to my heart, if I have a little doubt, never push it because there is always another day when you are ready.
Anyways, thanks for sharing and it's great accomplishment that you've overcame it before already.
