Have woken up a couple times confused and very anxious. Any thoughts on this?

If this happened just a couple of times, then maybe you just had a nightmare and it affected your awakening so much? If you are sure that these are symptoms of anxiety or severe stress, then you should consult your doctor about this. If you often suffer from troubled sleep, then I know that you can find herbal remedies that will help you improve your sleep, for example, on the Canada Drugs site you will find a description of them and how they affect human health. I know that some people still have doubts about CBD oil, but you can find other herbal sedatives on this portal.
