My dry eyes has gotten like 90% better, some days I don't have it at all and for the most part it's nearly normal now.
The trigger for me is things that cause tension, anxiety, anger. Almost 100% of the time. When I'm able to feel into those feelings it gets better but it doesn't go away. For me this is just the first step.
The second step is to feel safe internally. That might take time because it's your unconscious brain which feels unsafe or something similar. How we can cultivate safety is where you can journal, release pent up emotions, talk with people you trust, do things that not only make you feel normal but strong.
I personally believe we have to go beyond mere thoughts and journals because the amygdala learns through actions during times of stress. So we grt learning opportunities all the time.
