This topic is important, but it is also a huge area in which we lack the proper terms for describing what we're dealing with. I am absolutely no expert on any medical issue including mental health care, but I try to learn more about what I think is important.
Here's some reflections on "self medication" mental healt care and first aid:
My quick taste of unemployment (9 months) started as a cool volintarily "in between jobs" experience
(fun, challenging and educating experience as a proactive job hunter) and ended with symptoms that really should have triggered the "depression" diagnosis. At that point, I literaly crawled back to my old job to build myself up.
I always had my old job as a lifeline, and no substantial financial worries. Lots of unemployed don't.More than 10 years later and after a case of burnout syndrome in close family I am finally able to learn something: Your self esteem is important, and you should actively build it, expand it and make it stronger. Allow bad times (such as unemployment) to erode your sense of self esteem and you unleash all kind of trouble. Your self esteem is not about your job, your status or financial situation. Your self esteem is all about what you think about yourself, how you value yourself.
I sincerely believe that a robust mental health is important to help you live a good life in good times and keep you floating through bad times. We all have collected different kind of emotional luggage and wreckage through the years. Each of us have to find the tools to deal with that.
Mentally speaking, you are able to control far much more about yourself than you ever can imagine. You can convince yourself to change religion, political opinion or a bunch of other stuff. I think you also can also willingly chose to have the attitude that enables you to come through though times. And you have the power to control how you think about yourself and build your self esteem.
What about mental first aid for others?You tell me - I want to know...
For dealing with people that clearly are out of it I highly recommend the book "Verbal Judo: The Gentle Art of Persuasion." by George Thompson. His book was written for police officers, but the same techniques are applicable for any situation, including not letting domestic disputes escalate into a shouting match.
An important aspect in this book is empathy: You really try to understand what the other person wants and why he's upset. Having someone who actually is willing to LISTEN is a great thing in itself. It also provides valuable info if there's other actions that could help (quite often, listening IS the solution).
There's all kind of info available about how people react in a disaster - Susan posted some links that I think are quite relevant.
I think it is highly valuable to learn something about how the body physically and mentally reacts to an extreme stress situation. My best read on this subject has been "On Combat: The Psychology and Physiology of Deadly Conflict in War and Peace" by Dave Grossman. If I should sum that book up in a mental first aid perspective it would be that people who have witnessed traumatic situations need someone who can listen to them (pain shared is pain divided) and then tell them that their reactions are perfectly normal.
