Stop believing the lies you tell yourself.
I can't do this. I am not valuable. I am not loved, I can't achieved my goals. Something bad will happen etc.
We must replace these lies with the truths. I can do this. I am valuable. I am loved. I will achieve my goals. I am changing.I am changing to face the change. I will succeed, great things will happen etc.
If we do not nourish our positive thoughts they will die and turn into negative thoughts.
If we want our positive thoughts to live, we have to nurture and feed them everyday.
Negative thoughts are the same, if we don't nurture and feed them, they cannot survive.
