"Work the neurolymphatics for liver/gall bladder, under the right rib cage" means simply to massage that area. I would recommend massaging both right and left sides under the ribs, as the right corresponds to liver/gall bladder and the left to spleen. The spleen is a lymph organ, and can become depleted when we are stressed. Neurolymphatic reflex points stimulate the movement of lymph in the body in relation to the named organ.
The source points for gall baldder are in a little indentation on the outside of the foot just in front of the ankle bone in line with the fourth toe. The heart source point is on the wrist in line with the little finger. To open source points and make sure they are polarized, you can shine a flashlight on the point, flip your hand back and forth over the point, bring your finger tips together and rotate your wrist back and forth with your fingers about 3 cm above the point as if you were turning a key, or get a low gauss magnet shaped like a doughnut like Radio Shack sells and spin it above the point. All of these methods break up the energy and get it flowing well again.
If you know you have gall bladder issues, you can flush the gall bladder meridian on each side of the body. Google "gall bladder meridian graphic" on this site. Start at the end of the meridian, on the 4th toe, and trace the meridian backwards to its beginning point at the outside corner of the eye. Then trace it forwards 3 times. Repeat at least daily.
You would likely also benefit from a variety of stress reducing exercises.
