I really feel for you. I have experienced bouts of insomnia when I've been really stressed. I got laid off twice last year in a three month span, and even after I found a better and steadier gig, the stress persisted for a few months. Additionally, my wife was pregnant with our first child as I was starting the new job. Over the span of a few months, I would have week long stretches where I might sleep 2 or less hours a night, sometimes not at all.

I managed to work through it without using any medication, but it was only time and learning to trust that my body knew how to do the right thing (sleep), without my mind interfering, that eventually righted the ship.
