There's a difference between negativity and self-defeating thoughts. I believe this universe delivers to your door that which you expect to find. If you are always looking for the worst in others, and yourself, if you expect to find misery, negativity and chronic unhappiness, there it will be.

I see natural healing as nothing but "positive thinking", if you will, it's a deliberate dismissal of the doctor's assessment that drugs, pain and "treatment" is all they have to offer you, it is the ultimate display of positive thinking to dive into the unknown, to believe that you can be cured and not merely treated.

If you didn't have any reason to think positively, you wouldn't be here on curezone.
Don't sell yourself short - you've got light in you.
