  If this is a serious comment and you feel the need for 'trigger warnings', I suggest you take the adult approach and avoid material on the internet that may trigger you.  In other words, don't read the news or other sites you find offensive. This type of sensorship will help you avoid any potential 'triggers' in the future.  The other option may be to seek counselling to help you face your struggle instead of attempting to hide from it by socially constructing reality according to your specific, unique, individual needs.
