Anxiety messes with your sleeping schedule. Anxiety robs you of sleep. It can be hard for you to get a full 8 hours of rest when your mind won’t shut off. The disruption of sleep is likely to keep you feeling more on edge the next day.
In the morning, you might not get as much work done as you were hoping, because you are exhausted and that just adds to your anxiety. Sleep disruption is a common feature of mental health problems. Anxiety is no exception.
It’s a never ending cycle. This means that sleep problems can cause anxiety, and anxiety robs you of sleep.
