Having the Lunar Nodes at the midpoint of your Sun/Moon is very important info.
The Sun/Moon midpoint is the point of your emotional/physical balance. The state of your vitality and mental health. Your inner Ying/Yang. How you saw males/females interact and the role modeling they did.
When the midpoint is placed in Cancer in the 2nd, your family and childhood will have a strong impact upon your self esteem and your sense of self. It is that way for everyone. But it is heightened and emphasized for you, because of the emotional 2nd house placements.
In simplest terms, I would say that this incarnation, for you, is all about changing lifetime family patterns of dysfunction. The North Node compels you to elevate your consciousness, rise above old wounds, old ingrained patterns, learned in childhood. Find your spiritual path.
You came into this life to rise above those limitations and create a new path for yourself. BreaK FREE of what has been limiting you. Do not continue to be stuck in age old traditions and patterns and follow your own dreams.
If that means moving away or expanding/changing cultural routines or religious beliefs, dating people outside your tribe, or shaking up tradition, then do it.
The North Node in Cancer in the 2nd is about finding a way to rise above the familial codes/restrictions from the past and finding your dharma or your own individual journey.
