I can only tell you about CBD for sleep. I took it in 2017 and it did not work at all. I stopped taking it. Then in 2020 I started seeing a sleep psychologist. She did her postgrad at Stanford and is very science-oriented who checks every claim against available research skeptically. She told me for sleep, CBD does not have research backing and it was not surprising that it did not work for me. It is all hype surrounding CBD. But again I do not know about anxiety.
