Why do phrases like 'May I be safe' in Metta trigger fears of unsafety and anxiety?

When I repeat the words May I be safe at the self-compassion stage, my mind instantly shifts to all the reasons why I am not safe, my heart becomes fast and my anxiety soars. Apparently, the purpose of safety is to underline my weakness and powerlessness in the world. Will you replace this by a phrase referring to inner strength rather than outer protection?
