There's an exercise in one of Bruce's books. It's based in ascending energy from your feet to your heart chakra (through Susuma), and to redirect that energy through your arms/hands and collect it in your navel. I've experimented really strong sensations in my whole body after a session.

You might also try some reiki. Look for a master to be initiated (better for free), and try in yourself.

I know what you're going through. I'm also a computer scientist and I had to give up my job to start over in another thing. Nowadays I'm soooooo happy!

Good luck!
