Is it normal that my anxiety seems severe early in the day? and when im tired later in the day it is significantly less severe?

Variable anxiety: You know, everyone is different, and your symptoms probably vary depending on your environment, the people around you, what you eat, and many other things. If you tend to drink caffeine in the morning, that can be worsening your anxiety symptoms, so try cutting back. If you smoke, stop! You can learn techniques to master your anxiety when it flares. See a psychologist perhaps, or try meditation.
