Reddit reviews Care of the Soul, Twenty-fifth Anniversary Ed: A Guide for Cultivating Depth and Sacredness in Everyday Life

Dude, 12th-house Saturn has nothing to do with marriages ending. And your Saturn is trine Venus, not to mention you've got Jupiter in Libra in the seventh house! That all points to lucky and long-lasting marriage. I'm not sure what the heck you've been reading, but delete those links or toss out those books!

As for career, the basic gist is this: (1) understand your primal triad, i.e., the personality traits and needs suggested by the placements of your Sun, Moon and ascendant; and then (2) look closely at your tenth house -- the sign on the MC, its ruler, any planets located in the tenth, and what aspects they make. For the primal triad stuff, any good book or website will be helpful, but I particularly recommend Steven Forrest's The Inner Sky: https://www.amazon.com/Inner-Sky-Wiser-Choices-Fulfilling/dp/0979067715

You have Sag on the MC, which suggests a drive to find meaning and inspiration in your work. Neptune in the 10th also points for a need to inspire or be inspired by your career. Also, while your Moon doesn't aspect the MC, the fact that it too is in Sagittarius only strengthens the need to find meaning.

Jupiter, ruler of the 10th, is in Libra in the 7th. The orbs are wide but Jupiter could be considered to be squared by Uranus and Neptune in Cap and Mercury in Cancer. As IcebergTheory pointed out, transiting Pluto is conjuncting your Uranus-Neptune in the 10th and opposing your Mercury; also, transiting Saturn is square Jupiter. So yeah, this is career crisis time. It's about resolving this question: "How do I reconcile my idealism and my quest for meaning (Jupiter-Sag-Neptune) with the need to be responsible and act pragmatically in the world (Saturn-Capricorn)? How can my idealism survive the crucible (Pluto) of the real world (Capricorn)?"

Have you considered becoming an art therapist? Asking because I see both artistic interests/tendencies (Leo Sun in 5th, strong Venus) and somewhat futuristic or alternative healing vibes (Uranus-Neptune in 10th/cusp of 11th), as well as a strong interest in understanding and helping to heal other people (Jupiter in 7th, Chiron in 6th opposite Saturn in 12th; also, Mars in Virgo 6th suggests a strong urge to serve and heal).

If you actually are an artist, then this chart suggests that making art (paintings, music, stories, playing certain roles as an actor, whatever art you do) that inspires and heals people is a way forward for you. Teach and heal through your art. Read up on David Bowie to see an example of how that can be done: https://www.rollingstone.com/music/music-news/david-bowie-how-ziggy-stardust-fell-to-earth-183340/

If making art yourself is not your thing, then to me this looks like the chart of a teacher whose teachings concern human relationships and how to heal them. This could be very spiritual, a la Thomas Moore, who was a psychotherapist for many years and then took the wisdom he'd gained from that career to become a psychospiritual writer (one of his many books: https://www.amazon.com/Care-Soul-Twenty-fifth-Anniversary-Cultivating/dp/0062415670). Or it could literally be alternative healing (acupuncture etc.) aimed at healing people on a more than just physical level. Art therapy could bring both those things together.

Somehow the Jupiter in Libra in the 7th looks very important to me. That placement, plus the angular Venus, suggests to me that relationships are very important, and that your work should involve connecting with/working with other people rather than, say, working in a research lab or making things or engineering buildings or whatever. Being a psychotherapist might be a great way to bring together your urge to teach with your urge to heal and connect with others. And Venus rules your 2nd house, which suggests that earning money (second house) may be connected with relating to others (Venus).
