The moon's nodes have two axis, the north and the south. With two distinct meanings.
You have Jupiter conjunct the south node, and your nodes are square your midheaven.
Both the nodes and the MH are important points in a chart, so yes I would include them both if they are making signifiant aspects in the chart.
If you are asking about difficulties asserting yourself, the sun and mercury would play an important role here, conjunct in the 12th of subconscious, repression and difficulty of expression.
With Uranus on the ascendent, in mutable sagittarius, it might also be that you haven't been constant in your efforts.
Also, the Capricorn moon is known to be timid, although ambitious, but in a quiet way.
The south node is a karmic debt, it shows our past excesses, and often is active in the early part of our lives, until we let go and move on to the north node and what it is calling us to experience in this life.
Jupiter also rules not only your ascendent but also your 4th of home and childhood, so you were apparently strongly influenced during your childhood, either by your religious beliefs, values, and philosophy, or maybe you were overly indulged by your parents, encouraging you to be laid back and a little lazy (?).
At any rate, it was a starting point from which you have to move on, leave behind you and begin to explore the north node.
The NN is in Gemini of communication in the 7th house, ruled by mercury.
Mercury we already saw rules your MH and is conjunct sun in the 12th.
The NN in the 7th asks you to concentrate on your relationships, not on your personal expression. Mercury also ruling your MH of career and social status would indicate this is another area effected by these aspects that you have to apply yourself to.
Mercury being in the 12th works "behind the scenes", sublimely, subconsciously, and being conjunct sun it is overpowered by the energy of your ego.
It would seem these are the areas you have to work on, rather than your personal expression.
