You are what you think.
I agree. I think the lowest points in my life were those moments that I utterly lost confidence in myself. Waves of depression, stress and anxiety concerning my responsibilities and failures have always been the culprits of getting my self-esteem shrink to a size of a mustard seed. That would have been good if, like faith, a mustard-seed-self-esteem too can move mountains. But that wasn't the case. Carrying a 'mountainous' load, is more like it.
It's all in the mind they say. What you think about yourself affects the way you treat others, and vice versa. In the same way, if you're too occupied in thinking about how big the problem is, you might miss out on the abundance of the solutions available to solve it. For a pessimist like myself, this sure is a nice realization.
I guess I'll start out steering my mental vision to the bright side of life, with hope and conviction that things could lighten up a bit sooner or later.
The next time anxiety and depression attack, it is best to start digging what thoughts have crawled into our minds lately. More often than not, what destroys us is just what's inside us. Creepy, isn't it?
