Affirmations help to improve self-worth and self-confidence by replacing negative self-thoughts with positive self-thoughts.
Affirmations are conscious thoughts that you repeat to yourself. Often thinking can feel automatic, and sometimes your thoughts may not be as positive as they could be.
Worry makes you feel stressed and/or bad about yourself. When your thoughts become negative it is hard to feel good about yourself, or others.
It can be very useful to become more conscious of what you are thinking about yourself. By being conscious, and catching the thoughts you have as you think them, you can learn to recognise what is healthy for you and what is not.
