Building a wall and blocking out those who care are defense mechanisms I often refer to when my mind is drowning in a thick and heavy fog. Thinking becomes a painful nuisance and gives rise to headaches that make the minutest of noises unbearably irritating. Wanting to be alone, basking in silence, with no interruptions is all I want when I feel this way. Some people care and try to pry their way in, but silence and solitude is all I want. Can I not be granted this simple wish?
