Tears of tigers

The book I'm reading is tears of a tiger by Sharon M. Draper. On page 63 there is this amazing quote and it says," it's dark where I am and I cannot find the light. There are shadows all around me and my heart is full of fright." I really love this quote because it's like saying no matter where I am or what I do I'm always going to have this fright inside me and its not going away. It also said " ..I cannot find the light.." This really stood out to me because to me it meant like no matter what I do I can't find the happiness I had before. It's also like saying I can't find the key to life anymore because without the light then what can you see now?
