The thoughts and pictures we paint in our head can have a massive effect on our bodies, emotions, and behaviors.
If you conducted an experiment by showing someone a series of upsetting images or videos while hooking them up to a machine to check their stress levels, you would find a noticeable rise in their heart rate, stress hormones, and general anxiety
The same thing is happening when you have anxious thoughts, predictions, and beliefs about yourself, others, and the world. Thoughts and beliefs come into all levels of anxiety, whether that is ruminating about the past, misinterpreting what’s happening in the present, or predicting some terrible imagined future. Emotions are crucial to anxiety too. If we have a high level of fear, sadness, anger, etc., and we are uncomfortable with this, then we convert that to anxiety, thinking, and nervousness. Many of us never learn to tolerate our feelings.
But have you ever believed something and then changed your mind when you got more facts or evidence? Have you ever gotten more comfortable with something with practice? Probably yes! Just like the time you changed your mind about something, realized you were wrong when you got more evidence or became more comfortable exercising or driving, the same can happen with your anxiety. When you get anxiety help to challenge those beliefs, you gain comfort and knowledge of your emotions, body, mind, and actions. Then anxiety lessens.
