I do remember what it was like, but it has been a long time. Sometimes I will think about how I used to be so fearless, and didn't have physical symptoms of anxiety, it makes me feel like a totally different person. I remember how I used to love to drive long distances, and that it would actually relax me, then I developed a fear of the highway--even as a passenger. Back then I would sometimes encounter an anxious person, and I would wonder why the person worries so much, and I would feel sorry for them, and wonder why they just couldn't relax, now I am that person.
But, I love remembering how I was before anxiety, kind of makes me feel empowered :)
