Happy to help.
Re; The Saturn Return arrives in March 2020 so you have time yet to make preparations for the changes that may arrive. There is a choice involved in whether you adopt necessary preparations through awareness and understanding ahead of time, which could go a long way to helping offset the more sudden or unexpected potentialities of what might happen, or choose to leave it to fate. What is your concept about the separation of these two alternatives of theory?
You've had the benefit of having Jupiter transiting the Sun in the past six months and so this has been about learning more about your personality in contrast to your true Identity. Your Solar Return should have allowed some insights about how your identify yourself and how that impacts on the interactions you experience with others.
Saturn in Aquarius tends to carry lessons associated with independence and accountability in life and it's afflictions can leave feeling uncertain or harbouring fears about being left abandoned or isolated. These may be associated with inner psychological issues needing to be cleared out. Since Aquarius is all about freedom from restriction and restraint Saturn demands that you be accountable for knowing about the difference between between true responsibility and feelings of inappropriate responsibility, associated with inappropriate guilt or self-punishment. In the 8th H this is about hidden fears or complexes that hold you back from true progress. Consider also the input of the Saturn/Chiron themes.
I would offer though that you do have strengthening effects from a couple of lesser known aspects called Quintiles, involving support from Jupiter and Saturn to natal Pluto / Mercury. This allows you to be driven by incredible creative powers towards resolving your karmic difficulties [Saturn] and to become a person of power and influence [Pluto].
The quintiles provide great drive and momentum that ' push one to succeed in whatever you aim your goals at.' At the same time there is a danger of becoming obsessive and out of control, so they do demand a good dose of self-control to avoid going to extremes. Without it though, one can flounder in a 'sea of mediocrity', so the trick is to maintain some sort of balance over the intensity of the influences. For you that may well be offered through the square of Sun/Saturn, for self discipline and control.
When you remain unaware of such facets of your inner nature, it can lead to tragedies and missteps; as such you are apt to be driven to seek harmony in your life to avoid the pitfalls that may accompany it.
Pluto/Mercury gives you an inner depth to your mind, with the ability to come to profound conclusions, through deep insight and reflection. You have the capacity for deep research into the mysteries of life and psychological awareness, which can be very helpful in your Chiron issues.
You recently experienced your Solar Return, which serves to re-charge the natal tendencies of your Sun, igniting the inborn challenges between the Moon and Saturn, afflicting your personal sense of Identity and Purpose in life. That gives you the incentive each year to re-evaluate your progress and the goals you are striving towards. With every cycle, important lessons are meant to be learned.
Astrology demonstrates the implicit importance of cycles in our lives. Changing our lives becomes easier when we can recognize that life is about 'spiraling upward' rather than being fixed in a straight line and doomed to repeat the same mistakes over and again.
Each planet has it's own cycle with a different time frame, and this also affects the timing of our stages in life. If we don't attempt to clear out the 'inner blockages we carry, similar problems will be 'coming around again'.
With effort and awareness the Saturn Return can serve to release us from our inner torments that stand in our way and keep us fearful and uncertain. The slate can be wiped clean again , so we can being our next cycle with greater wisdom and clarity. Feel free to ask for more input from me, as you wish.
