If you are struggling with depression or know someone who is (which is not as rare as you think) I recommend this book. Though depression looks and feels different on different people, the author has managed to accurately paint a general picture of how harrowing and lonely depression feels like, basically an internal battle with your own mind. The author also lists things that helped him find a way out of his crippling mental state and it sort of gives hope for everyone who feels like there is no light at the end of the tunnel. It is a comparatively 'small' book but definitely NOT a light read!
