The only evidence I've ever seen about influencing CBD levels is that some recent lab testing has shown a possible correlation between harvesting early and higher cbd to thc ratios. They theorize that CBD forms earlier than THC in the plant.
There is a *lot* of misinformation out there and it's repeated regularly by people so it takes on a life of it's own. Read the information here Medicinal Cannabinoid FAQ: What are THC, CBD, CBN, CBC and
to learn about what THC and CBD and CBN etc actually are.

And most importantly deal with your anxiety now, there are three easy things you can do that will make a world of difference speaking from deep experience with the same issues:
1) Get outside and get some exercise, really hard intense exercise. Look up Tabata Sprints or do what you want but it better be incredibly intense (like almost puking intense and put a *lot* of stress on your body) and short, no longer than half an hour (Tabata intervals only take 14 minutes including a 5 minute warm up and cool down).
2) Next most important is getting enough sleep which is hard if you don't do the exercise and end up sitting awake stressing which is why I put exercise first. Shoot for minimum 8 hours a night. Latest research confirms that it's ok if you split it up because you wake up in the middle of the night so don't stress about getting 8 hours in a row, just 8 hours total.
3) Third is cutting out anxiety producing foods like sugar, caffeine, high glycemic carbs like whole wheat, grains, rice, potatoes and eating more vegetables and meat instead. Look up a ketogenic diet for details, it's commonly prescribed to epileptic children to cut back on their seizures but also for losing fat quickly and everyone on a low carb diet always reports clearer thinking and feeling calmer where before they were filled with anxiety but didn't realize how much until it was gone. Once you've done that for a few weeks you will feel far better and can then look at switching to a "Paleo" diet which is long term sustainable and incredibly healthy besides.
It took me a *lot* of time and effort to learn to control my anxiety and if you do those three things I absolutely guarantee you will feel tremendous relief within days or your money back.
Good luck and take care.
