it seems like what the artist trying to say is that many people are being abused both physically, and mentally, but they don't talk about it. They try to 'hide their scars', and they keep their emotions to themselves. Some of these people are never going to ask for help and are also ready to just give up in life, but the artist is trying as hard as possible to save the victims by 'holding on' to them, and talk them into not giving up, to have hope etc. I think that another message of the video of this song is saying that these terrible things are happening to people around us every single day, but we are 'blind folded' and we are just isolated in our own little happy world and are not opening our eyes to see the bigger picture.
