Don't worry about tomorrow, focus on now.
Do you suffer with anxiety?
Then you're worrying about something that you only believe might happen, a possible, self-predicted outcome.
Try and focus on the moment, stay in the now and take your mind away from what's troubling you.
Stop listening to the inner you who spends all your waking hours telling you you're not good enough, and try your best to step outside your comfort zone, feel the fear and do it anyway.
Small steps first, you might just surprise yourself.
