If you are actually looking for honest advice with dealing with anxiety seeking out a professional is the best option here. Be it a general therapist, psychiatrist, or psychologist. A good way to go about it is to speak to your local GP/Doctor and they can likely recommended you to someone with a referral. There are many methods that can be beneficial for some but not everyone. Everyone is different and there ad numerous different kinds of anxiety. A professional can help find what is best for you, if that is working, and modify along the way.
My advice is do not go with CBD. If you are prone to things such as psychosis, even without knowing, there is a risk there. CBD likely can even make your position worse. And even in general going through something as CBD to try and help rather than a professional is quite irresponsible for your personal mental health.
