Hi,
I came across some information in one my qigong books that spoke specifically of chronic tearing. I wanted to offer it up as a 'possibility':
"Chronic tearing is the result of blocked tear ducts. Not blinking will stimulate tear production, helping to cleanse and remove blockages from the tear ducts."
When I read this, something from SFQ came to mind. It had to do with sensations you can experience while doing your exercises/meditations. Like an itch somewhere. The point being not to scratch it, and let the energy do what it is doing. Turning this all to a positive healing message, would find you doing your exercises, and if during or after, your eyes water,,,,let them, and support that with positive messages and allowing them to water. Again, versus a negative reaction to a perceived irritation, or rubbing to interrupt that releasing going on.
Good, better, best gives you room to be flexible. If you aren't in a qigong session, and they start to water, try to take a moment to allow the energy that is moving to move, and support it with healing messages. Even just a moment. See if your sense of what's going on starts to shift towards your moving through something, and if your positive response helps you see improvement over a longer cycle of time.
Increasing your active exercises is a good way to accelerate physical healing. - g
