I understand what you are saying, but I cant agree on you because of two aspects. First of all, it didn't bother me at all when I first listen it because it was really the way I wanted to sound. Secondly, the anxiety title does not refer entirely to the more animated middle section, but to the harmonic variations and extremelly anoying repetitions on different octaves like the final bars. That recap is just a musical technical I use to write my pieces with short duration, so It does not influentiates that much the anxiety theme.
Think about your narrative arc for a moment: The entire middle of the piece is a musical representation of anxiety, right? Well, in real life, once an anxiety attack has come and gone, you're not just instantly calm again. There's usually leftover nervous energy. The calm isn't complete, there's usually something still stirring under the surface.
When it comes to a recap in a piece like this, where the contrast between the subject and its development is significant, there needs to be some sign that the journey the listener just went on matters.
