MD, you used the words "roller-coaster" to describe the last few days... A "roller-Coaster" is a great example, and for everyone - a "roller-coaster" is a good exercise in breaking this addiction. We often want to pleasure ourselves to feel we are in control of our lives, and we don't let ourselves break free until we are finally willing to "Let go and Let G-d". On a roller-coaster, your life is not in your hands. You must totally trust those who built it with your life, and as you are hanging between heaven and earth about to fall straight down, you need to just "let go and trust". This is a very good exercise for anyone who has trouble "letting go and letting G-d".
And what you did recently, MD, is just like a roller coaster in this sense. You knew you were jumping off a cliff, but you trusted Hashem to catch you. And I am sure he did/will.
