Description of a panic attack

Hi all! This 3 minute unfinished piece has been in this forum few years ago , but i wanted to share it here. Someone then said that it is just a series of dissonances. But there is a reason i like this piece - it is a description of panic attacks i had few times when i was younger. (I haven't had those for years luckily. ) Its purpose is to invoke that feeling.  I could make this less messy, write it for quartet or quintet for example that way that every player has meaningful lines. But i think that the red line of the melody is there and it is logical even when some instrument plays notes that sound like exaggeration. But even then this would be difficult to play.

I don't think the idea is bad at all, and I think it is well expressed.
But from a musical point of view, the piece, short as it is, may need certain contrasts that somehow change the level of tension.
In part I think it does for 1:00 where the level of dissonance is similar, but the intensity is milder.
Perhaps I think it would benefit from some cadential moments (which by no means should be tonal), because it's like a forward continuum the whole time.
