Well, the overall shape of your chart might incline you to be focused more on your inner world and your own concerns rather than with the big bad world Outside: it is a bowl-shaped chart, with everything below the horizon - here, if you want to follow the traditional wisdom, the NN would be there to drag you kicking and screaming into this larger world of Career, Others, and the rest, asserting yourself and making your mark there.
The Moon on the Asc in modest and timid Virgo suggests a good deal of sensitivity to the atmosphere and the vibes around you and any sense of being disapproved of could see you scuttling into your shell. Virgo can be an anxious sign anyway and with the Moon there, it might mean that it is issues to do with separation that could trigger this?
On the other hand, there is a rather outspoken Mercury-Mars conjunction in Aquarius too, suggesting that you may be concerned about negative reactions to comments made without thinking. This, with the Virgo rising, indicates to me that you may have a pretty tart way with your observations, but then be a little freaked out by the reactions you may get to these.
I also see that Venus is on your Saturn-Pluto midpoint too. In expressing your feelings towards other people, this could be a little inhibitve too.
What was school/late adolescence like?
