That's a very interesting write you have here, Ernah. It clearly has an immaculate flow and a good message. Loved the simile.
But I believe you should write a note up there or beside the title that it's a sestina, because I was confused when I finished reading the first three stanzas and I went a bit critical in my head. People may lose interest in reading on if there exist few reptitions if they're not really well-done or required, so in your case, a note wll do you a big favor.
I also guess some lines were too long and they felt forced. If you take a look at them again now and try to fix them, it might work out. I guess.

I missed your writes and your existence in here. Be more active.
