Hi fmiss,
You have posted a thread some years earlier about studying to become a music-therapist, did you become one?
I really like how that kind of a job fits nicely to seeing your nodal axis lined up, Pluto and it's opposing point, ruled by Venus in the 5th. That's one way of looking at life path and where the question comes from.
As for the intensities you describe, have you noticed the Pluto transit in the last years? Over the north node, the descendant and that means that it's opposite the ascendant, has been opposite Chiron for some time some time ago. That pluto energy is very much like what you describe, both intense and phoenix like. Building then burning, perpetually. The fire in your chart has some strong points, Sun trine Asc, MC in Aries.
You mentioned Neptune. It is transitting your 9th house for some time now. Dissolving what's there from time to time, making space for new things. The 3 - 9th axis is involved with the mind, right brain and left brain hemispheres if you will.
I would imagine that Mercuries placement and relation to Jupiter and Pluto also comes in. Jupiter blows the thinking and communication about that out of proportions like a balloon, then Pluto pops the balloon through the semi-sextile.
If work/career gets simplified to the MC. It's the Moon in sextile and Jupiter in trine making it easy to start to like a lot of things. In some sense you seem like a high spirited person, I love that you write that you love to be alive. In a mental way so Sagitarrian (or fire signs) and Jupiter,Sun, Venus Mercury. Excited somewhat fast perhaps.
Then it seems your Neptune dissolves as fast, the square to the MC is not in the chart but it's an aspect in your chart none the less. Drawing the energy towards the 6th house of health.
The excess and nothingness shows up here as well with Neptune (nothing) quincunx to Jupiter (excess). It's like you can't see both at the same time with this 150 degree aspect. Going into one ór the other, never both. It's maybe telling that the center of this is in the last degrees of Libra (and Aries). Finding balance at home, within your basis. That this point is square to the nodal axis, adds up to my last paragraph about a possible deeper level.
Maybe strange as a notion but I think that Saturn is your friend in all this, or should become one. Strong in the capricorn and the 6th is not all bad, it is self empowerment, it is also the way you go about your things in daily live, routines. All the rest in Capricorn have a bit of an uprooting nature, your chart in general can be read as that as well so Saturn there is a real anchor. You may want to invest in getting that energy right for you. In a balanced matter offcourse. Themes like earth, grounding, nature, structure and reality, this world and not what you think or dream of it.
The earth theme comes back in a possible resolving of the trouble the T-square (Moon-Jupiter and Pluto) brings. It asks for you to get into the Taurus energy a bit. Just in the 10th house. The way you show up in the world, stay grounded there, know what you want and like, stand for that (keep it nice, creative and flowing though, Venus in the fifth).
There is this possibility that some things that are coming up are coming from a deeper level, a soul level if you will. That's with Chiron on the south node and Pluto powerful in the Scorpio fourth. But that way of dealing with stuff is not for everybody, meditation, seeking out a healer (that can be a therapist,coach or something just as well).
I get the idea that working on getting to know yourself better, self development with a coach might really help you.
This world is a bit of a strange place, that strong alienated feeling can maybe come with the Chiron and Pluto placements as well. For reasons mentioned as well as they somehow point towards some trouble with getting born. Maybe the actual process of labour when you where born or having some trouble to match the body to the high spirited soul you are.
