I also had a really bad year in 2012. At the beginning of the year, I was just generally depressed and have past trauma that I had to deal with. Most likely due to the approaching Saturn return first reached my natal 2nd house and square my natal moon in 5th for quite a while, natal moon in Capricorn so the Saturn as the ruler. That was a period of low self esteem and challenging of my new relationship (Saturn activated a new romantic affair but it was painful for a long time).
Later on the year, I was hit by careless scooter driver when I was crossing pedestrian green light. It was 11 days after my 2012 November solar return. As a result, I had surgery on my right fracture ulna bone, plate and screws were used for the internal fixation. Cuts on my right ear, massive bruises on right arm, right hip and the whole right leg with quite a lot of scars. It showed in the Solar return, Lunar return even the surgery time was showed. It was rather interesting in term of learning astrology and for future predictions.
I had 6 weeks off work but had to force myself to go back to work before I finishing off all my sick leave and the fear of losing my apartment and fear of unable to pay mortgage that was related to the Saturn transiting 2nd house so I had to take action to prevent it got worse. So with logical strategies I saved my annual leave in case if I don't cope well.
I was right and I even afford to save good sum and went to UK for 5 weeks holiday to visit my boyfriend this year during late May till early July.
The outer transit Uranus Square Pluto from mid June would be the possible major transit that might had activated some unpleasant events for many people in this thread.
My own accident occurred on 21st November 2012 at 1900-1910pm, when Uranus square Pluto was in 3 square orbs, and transit Mars in Capricorn was approaching Pluto as conjunction in 5 orbs then 4 orbs when the surgery occurred and square transit Uranus in the 7th cusp. Uranus was also in inconjunct with transiting Saturn. Transit Venus was squaring my natal moon, conjunct my natal Pluto (ruler of the Sun, Mercury, Saturn and 3rd house), in natal Pluto Square Moon, so also square my lunar return moon, the driver was a young female.
Since it was so soon after my solar return, in solar return, Scorpio ascendant, Saturn on ascendant inconjunct Uranus in 6th, Venus Uranus and Pluto was the T-square in the solar return, with Pluto (ruler of the Sun , solar return ascendant and lunar return descendant) as the leg of the square in the 3rd house. Jupiter in Gemini Rx was in the solar 8th house while Mercury in Pisces Rx in the solar 1st so ill mutual reception for Jupiter and Mercury. Sun was in the solar 1st house, so health and physical matter was the focus of the Solar Sun.
In Lunar return 18th November chart, Mars in Capricorn was in 8th house, ruler Saturn in Scorpio on DC, Lunar Sun at exact conjunction of the ecliptic point on 13th November, Mercury Rx also conjunct both NN and Sun in the lunar by 1 orb so clearly Combusted. So both Sun and Mercury were clearly eaten by the Eclipse. Sun, Mercury Rx, Ecliptic point, Saturn were all inside the 7th cusp it was saying "The Other Person", my vitality, my Mercury ruler of my natal chart were harmed due to the 7th house person of the month. Transiting Neptune also square the Lunar Sun from 10th house, Neptune conjunct Chiron of the lunar, weakening of the Vitality. There are many midpoints also, won't mention here.
In natal, Mars in Virgo is in mutual reception with Mercury in Scorpio in 3rd house. Mars also in mutual reception with Moon in Capricorn in 5th by trine, Moon in Capricorn sextile her fall Mercury in Scorpio. Ascendant is Virgo and MC is Gemini. At the time of accident, it was Mercury retrograde which was in conjunction with my natal Sun.
Mars is the natal 8th house ruler for Aries cusp. I had 2 more minor car accidents within the last 10 years period before the little more serious one last year. Thank God the solar return Pluto in the 3rd house leg of T-square was conjunction with Part of Fortune.
