Well, first of all, you did a great job answering part of your own question. Two-thirds of your trinity is in Cancer, a sign of extreme empathy and sensitivity. Your Virgo sun is very rational, Captain Spock in Star Trek was portrayed as a Virgo, as the planet Vulcan is believed to be out there somewhere, and to be the ruler of Virgo. But this is your rational and intelligent part. It's a good combination, and don't forget the other planets are all in a zodiac sign too--I just can't accommodate that length of time for interpretations here.
Being a Cancer sun myself, this is what I did when I began learning astrology. The ruler of Cancer is the Moon, and it moves fast, through all 12 zodiac signs in 28 days, give or take. So it changes moods and attitudes for periods of 2 and a half days. Llewellyn publishes a great Moon Sign book, and also a calendar, which tells you exactly when the Moon changes signs. It also tells you when to do what things, as in what works well when the Moon is in each zodiac sign. I recommend the Moon Book, it figures out all the time zones and has a plethora of info about the Moon which will help you. When the Moon is in Cancer it's probably your most emotional time, so visit family, help someone who needs it, cook a meal for a sick person. When the Moon is in Capricorn, balance your checkbook, do sensible things. I recommend this book often (no, I'm not on Llewellyn's payroll)! I also wrote an article regarding Moon signs, but I couldn't continue with info as to all the changes. Here's the URL:
