In England the BACP are the registration body you should look for if you go private.
Short courses of CBT for anxiety should be available on the NHS - either see your GP (and you may need to push this) or self-refer. A web-search of your county and terms like "IAPT" (improved access to psychological therapies) or "talking therapies" should return your local number.
You might find good results after a short course - 8 to 14 weeks.

It's easy to think of anxiety as being a mild disorder, but it can become pretty severe. OCD is an anxiety disorder and that can hospitalise people.
I like your list of lifestyle interventions.
