You have a moon/Chiron conjunction in Scorpio, trine your sun. That does indeed suggest a draw to dancing with the dark side, working with taboos and shadows. Water signs tend to have a lot of empathy, not just sympathy for others, but in water dominant individuals, there's usually a strong tendency to experience others' emotions as their own, sometimes to the point that your own self seems to vanish. The urge to merge is particularly Scorpio in nature--Scorpio is all about going deep and deeper and deeper.
Because your dominant chart elements are water and air, with almost no earth--just one planet and your ascendant in earth signs--spirit, emotions, and ideas are where you can work very well, but you don't have much resource of your own to ground those emotions and thoughts and make them work in the real world. To do that, you need the help of others, and you need practices that connect spirit with material. Perhaps something like tai chi or yoga or moving meditation--that is, a practice that's simultaneously physical and spiritual and could be done both alone and with others.
Here's what leads me to recommend that kind of practice for you: your north node, which shows us what you want and need to bring more of into your life, is in practical, earthy, daily-practice-oriented Virgo, in the eleventh house (groups, people who can help you get where you're going) and on the cusp of the twelfth (spirituality, withdrawal, ultimate self). It's also absolutely necessary to get yourself grounded if you're going to do any kind of shadow work. In the absence of grounding, shadow work would just draw you deeper into the shadow and out of touch with reality. To do it, you don't just have to be able to go into the shadow, which comes naturally to you, you also have to be able to come back.
Do you have any practice already that would fit the bill? If not, is there something you're interested in taking up that would?
