Hello Tommy. "PAWS" is mostly just a catch-all term for a wide range of symptoms common to those in recovery. It is not a diagnosable condition from either a physical or mental health standpoint, that's why your counselor/therapist probably doesn't know much about it.
It is definitely common to feel like you do in early recovery though, I dealt with all kinds of crazy stuff including anxiety, panic, etc for well over a year before I finally got a handle on it. I think it's great that you are seeing someone - are you working on any therapy our counseling in addiction to the SSRI?
