Some people suffer from symptoms similar to post-traumatic stress disorder (PTSD)with worry, disturbing and intrusive thoughts, hyperreactivity, hypervigilance, grief, sleep problems, and nightmares-but in this case the symptoms stem not from a traumatic event or series of events but from how it feels to live in today's world and from anxiety about what it could be like in the future.
