To resist the onslaught that these people aim at you requires an almost superhuman effort. I once heard it described as standing in front of a nuclear explosion with only a paper bag for your defence.
They are so sure of everything, and you are the one that doubts everything...it's no wonder it's all so difficult. And it's no wonder that the effort required is so constant, when it would seem like such a blessed relief to cave into it all.
Well, you have survived and you are here because deep down there is the tiniest, hardest, indestructible belief that you wanted to survive, that you weren't done with life, that you had more life to live. That my dear, is self belief and self worth right there. And on that, the rest of you stands. Be proud of that.
