Hi Will and welcome to the forum!
Sorry to hear you are still having a tough go of it.
I had problems with PAWS when I quit drinking, but not so much with pot. It lasted for about a year for me.
This seems like a really long time for you to be still dealing with it, but you may be one of the long haulers.
But perhaps your anxiety is an unrelated issue. Have you consulted a doctor?
P.S. I think your English is fine. I wouldn't have guessed it was not your first language if you hadn't said so!
