Dr. Franklin shares some really good information, about warning signs, and resources for help with suicide prevention, but maybe the best reason to read, and bookmark, the article is this one:
Now is the best time to start building a collection of resources that you may need one day for yourself or a loved one. Suicidal behaviors can happen at any moment, so instead of waiting until you truly need them, I recommend finding some trusted resources now to become familiar with.
So, read it. Click the links, and read some more. Bookmark the stuff that matters. Re-read it a few weeks from now, a few months from now, etc.
It might just save a life.
