One of the key symptoms of depression is to see no hope. No future. Far from the tunnel having light at the end of it, it seems like it is blocked at both ends, and you are inside it. So if I could have only known the future, that there would be one far brighter than anything I’d experienced, then one end of that tunnel would have been blown to pieces, and I could have faced the light. So the fact that this book exists is proof that depression lies. Depression makes you think things that are wrong.
