I personally feel that while we can certainly have these types of symptoms at periods over time ( I did! ), that "PAWS" is sort of a catch-all when we don't really know what's going on. Kind of like when you have a runny nose, cough or just feel down and chalk it up to a random "bug"
For the most part PAWS is just a term, it's not a diagnosable medical or psychological condition. There is no known cause or solution either. However, it's very possible to be proactive on the symptoms. If you are feeling depressed, you can absolutely seek help for depression. Same for anxiety or any other psychological ailment. If you are feeling physically sick, you can seek medical help.
