Have you ever met someone with a TBI? Do you even know what TBI stands for? I can vouch for the effects of a Traumatic Brain Injury, this very short paper deals with the depression that can sneak up on the survivor.
'Jax_Teller' has written a very deep and emotional story, 'The War With Depression' even though it's relatively short.
I do not know if he has had a TBI, his writing says he has. Being one of the warriors who suffer from a TBI and the depression that can kill you, I strongly recommend that you read this short story. Just for the information if nothing else.
