I don’t think this chart says you are a ‘terrible person’ at all. It is a very difficult chart that you chose for this incarnation though. It is not an easy ride.
You have nine placements in Earth and Water, and very little in Air/Fire. [Only Mercury and Saturn. ]
That discrepancy/imbalance can create the level of discomfort and dissatisfaction that you describe. Water/Earth dominance can create a somber, security oriented, fearful outlook. “Self-Protection is the number one motivator in a strongly Earth/Water chart. And to do that , one must be serious, hard working, and be conscious of daily survival necessities/resources. You would be conscious of security issues and potential downfalls, mishaps, possible upcoming problems. It is hard to feel any level of happiness or satisfaction when dealing with these kinds of fears, concerns on a daily basis. Most of your energy/resources must be reserved, maintained, set aside for basic survival, in your belief system.
The positive thing is that you have incredible endurance, persistance, strength, and are an incredible survivor. Most of us have not had to endure your past trials and tribulations, most likely. [ And they were not of your making, most likely.]
{ One very weird thing——I have 21 Taurus rising and my Moon is 3 Cap—]
Your chart ruler, Venus, is in the 3rd @ 29 Cancer. I don’t think the last degree of Cancer is ever going to feel emotionally fulfilled. You did not come into this incarnation to feel satisfied. I think you came to pay penance. And to care for others.
It is disposed by your Cap Moon in the 8th. I have a 3 degree Cap Moon in the 8th as well. I don’t cry when I should and I do cry when I shouldn’t? My emotions are hard to unravel. But I am deeply emotional—stress the word deeply. Sometimes tiny things make me cry uncontrollably. But a huge tragedy may leave me frozen in time.
Mercury and Chiron are your only FIRE. But the are prominently placed in Leo in the angular 4th. So you may have lofty goals, aspirations/expectations, for what you plan to accomplish in your life. With the Sun/Venus in Cancer in the 3rd, and the Mercury /Chiron in the 4th, you might have been expected by family/siblings/teachers/friends to be successful, prominent in some way.
But those are very challenging squares/oppositions from the malefics. It’s no joke to have Mars/Pluto opposition exactly upon your angles. And then Saturn comes and lurks, watching , to make sure the failure/upheaval/delays are complete. Life has been difficult. The Earth grand trine can help elevate you somewhat by perserverance, motivation, hard work.
Jupiter in the 5th, ruler of your 8th, can add the creativity, metaphysical faith and optimism needed to push through. Transiting Pluto has already plowed over our Moon—and now it is taunting your Uranus/Neptune conjunction. I think it is a good thing in the end. You can let go of a lot of old baggage and feel a sense of renewal. That is hard to do when we are mostly water and Earth.
Tune into your fiery Mercury and burn through the past bad memories. Release them. Time to move on.
Draw up your progressed chart and evolve! Pluto is giving you the gift of the Phoenix by plowing through your 8th.
I don't know how to talk to people. I don't know if I like a lot of people. I don't know how to say that I want things, I constantly offer that I'm down for whatever and have no opinion -- if I really want something, I don't ask, I get it myself.
