Hi! I see the trauma in more aspects than just the 4th house.
First, your moon (emotions) forms challenging ( T-square) aspects with:
1) your north node (trauma from mother, or female. By her presence, or absence). This affects your relations with women (moon in 7th). When you disagree with people, you take things personally/emotionally = it doesn't help you to resolve differences.
2) moon squares your stellium in scorpio, especially your mercury neptune, and a little less your sun venus. I find neptune as the decisive factor here, as he generates "fog", e.g. deceipt, disillusion, related to both your father and mother, or male/female figures. By instinct, I'd interpret your father figure being more passive, i.e. likely substance addiction or disease that requires heavy medication. Since your moon squares neptune, I'd interpret the mother figure being not in tune with reality. Either impractical, dreamy, artistic type, or subject to deceiptful behavior (she may not mean it, but this is how you experience her).
The good news now, involve your hypersensitivity, strong instinct, making you a suitable ARTIST with this stellium. Working from home would be awesome. Theater, art, dreamy inspirations.
Remember, your stellium is ON YOUR SOUTH NODE = past life, or early life legacy. This means that you are shifting/drawn away from this, and are destined to feel more complete when you get over all this, and focus on Taurus, and your north node conjunct MIDHEAVEN = CAREER SUCCESS.
Use your wonderful Pluto, Mars, Uranus conjunction, which makes you very powerful, resourceful, stubborn, and power-driven, to succeed professionally. Remember, these 3 planets form sextiles (positive aspects) with your stellium, HENCE YOU HAVE IMMENSE POWER AND THE ABILITY TO GET OVER THE PAIN.
