When I am especially tuned in and present, I sometimes notice the still small voice within me, say "Watch yourself". I don't take this as a cautionary warning that I may be harmed or may harm someone or something else, but accept the message as words of encouragement to stay awake and find things to appreciate.
In the years since I have made it my intention to live my life in a state of awareness, I have come to learn that the more in-tune I am to what my thoughts are, the more control I have in steering myself in a direction of thought that feels good.
Many people will argue that last statement, defending that their status of happiness is not fully in their control. Believing you are a helpless victim of life is not likely to be pleasant.
My suggestion to those that find themselves drowning in a sea of scary thoughts, is to look at one thought at a time. Be curious about it. . . where did it come from? Are you focusing on beliefs that others have taught you? Are you replaying news clips from Fox news? Is it simply easier to think the same frightening thoughts since that is what you've always done?
The good news is once you are committed to watching yourself, you may be surprised to find you do indeed have control over what you think. Remembering you are the creator of your thoughts and therefore your experience of life (no matter what is happening around you) is a gift we each have every day.
So watch yourself and see how it feels.
