Mark you are a a brave wise man.
Brave, because FEW people can admit that they do not know what they do not know.
And wise, because you do not wait to have something happened in your life in order to understand it, but you get knowledge by people that had been there — and you move on.
Again, few people have those 2 talents and I wish you all the best in your life indeed.
BTW the KEY that helps someone with a depression is: LOVE. And THEN meds.
