Anyone who's lost loved ones and been traumatised in a tragedy like this is likely to suffer such feelings (and others associated with PTSD) and will need a lot of help to overcome them and move on. The only way to start that process is to admit it and seek help but a lot of people find that very difficult indeed and the necessary resources are clearly going to be under great pressure given the likely numbers involved which will no doubt include a good number of emergency services personnel who were called into action that night and had to make the most awful decisions.
