What is your approach to problem-solving? Do you gather information you may need ahead of time, just in case? Do you wait for a snafu and then ask people for advice? Or perhaps the time to deal with a calamity is when it happens and you tear your hair looking for answers.
Most of us come predisposed to follow one or another of these problem-solving methods. Whether or not there's an ideal way is not the question; how you manage and get through the crisis is what's important.
Accidents, critical illness and death strike when you least expect it. The devastation it causes to mind, body, and spirit makes gathering information more than difficult. You simply clutch at straws, unable to think straight anymore. That we manage at all is remarkable, but it's not necessary to heap more distress and anxiety on ourselves.
Knowledge really is gold. Start to accumulate information on the effects of crisis, trauma, illness, and death that ultimately hit all of us. There is an abundance of books and articles on websites, social media, author and grief sites. Store up some gold for yourself to spend when you need comfort and support. And, while you're at it, encourage those you love to do the same.
