I vow to let go of all worries and anxiety in order to be light and free

I read these words and immediately thought, wow, that is going to be my new mantra.
But, can I really do it. Can I set aside all of my worries and concerns to lighten anxiety? Will this simple sentence fix all of doubts, concerns, worries, and fears?

Will a simple sentence take the place of Xanax?

I can certainly incorporate it into my daily meditation and work on this day by day.

As in everything in my life, I can try. I can do. I can learn from my endeavors.
