It doesn't take much to set our minds going though does it!
What else could it be that is causing anxiety? Lack of sleep? How is your diet overall? Do you exercise? Work problems that might be niggling? Anxiety for me is due to not eating properly or at the 'right' time for my body. Think of a baby who cries when hungry. My body is like that, "feed me now, now, now"
otherwise I get that gut lurch = anxiety.
Have you tried deep breathing, that worked for me years ago. Yoga helps some. Brisk walking. You are not alone!
