Everybody responds differently to THC; so, what’s best for someone else, most likely won’t be best for you. However, that 8:1 product would be an excellent choice to start off with. Each dropper-full should contain approximately 16mg of CBD and 2mg of THC. To avoid getting high and forgetful, I would likely recommend that you start with 1/2 of a dropper full (about 10 drops) which would provide 1mg of THC and 8mg of CBD. If that does not provide much anxiety relief, you can increase the dose to one full dropper.
Hope this helps!
