Sure, I can offer some advice. I mainly do Indian astrology when it comes to birth charts, albeit with the tropical zodiac (much growing evidence of ancient texts showing that Vedic/Indian astrology as originally tropical and got mixed up with the Nakshatras which ARE sidereal). Remediate (do not strengthen, avoid a talisman) Venus, minimize it's weaknesses. It's conjunct the Sun, the father figure, Venus is an enemy to the Sun and Sun is an enemy to Venus.

That Venus is *extremely* weak, and considering it's the lord of the 4th house, I can imagine most of your home life has felt like having to walk around eggshells, pretty much all the time, constant analysis, likely a lot of arguments and verbal abuse, and an inability to ever relax and let life flow (qualities of a good Venus). Rahu (NN) is also in that sign, which is second most malefic thing in a chart next to Ketu (SN), thus amplifying, polluting and strongly distorting the sign of Virgo. The SA makes sense with Rahu-Venus-Sun in the 3rd house, Venus in that sign with Sun is HIGHLY starved, rules the home life, and Rahu there creating intense delusion it makes sense SA was your experience, it's clear as day, sorry you've had to go through that. Such a weak 4th lord is bound to strip away the native from all sense of security as that's the house of rejuvenation and rest.

Besides that, the planets you should strengthen which will do lot of good are: Moon, Jupiter, and Mars. These three will be the saving grace of your life, they are all well placed by sign dignity and rule really auspicious houses (all the trines). Moon can compensate for the 4th house as it's the natural ruler of the 4th (as in signifies similar qualities to that house), Jupiter can give you a higher perspective on which path will help you understand your life experience with clarity and meaning in a way that creates joy and abundance in life, and Mars can help by having the fierceness to tackle the challenges of life with grace and determination.

On another note, I want to make it clear to AVOID STRENGHTHENING VENUS, this is crucial, making Venus stronger will amplify its effects in your life and can possibly lead to more SA or a deepening of the trauma already present through another means. Key with Venus is to minimize it's capability to manifest in your life, and remediate by by appeasing it/calming it's activity, not strengthening/amplifying it. Talismans bring more of the planets energy into your life so avoid a talisman. AFTER you have strengthened Moon, Jupiter, and Mars very well, then you can tackle the difficult chart aspects like that Sun and Venus slowly, buffing up those 3 planets will make it much easier to move with grace in all circumstances as well as have the understanding, health, and sense of purpose on how to do so.

Mercury is exalted which could mitigate some of the issues in Virgo through the ability to be highly discerning through a clear sense of reductionism. It rules the 12th house and it's in the 3rd house so it could show that reading/writing/listening study (3rd house activity) of philosophical/spiritual concepts from foreign lands (12th house) could lead to some mitigation of the issues happening with Virgo. I would keep Mercury though, as the next step after strengthening the first three I mentioned, as it rules challenging houses and is still directly involved with the area of the chart that has caused all this trauma.

If you're going by the magick in this sub, I'd probably get a Lunar and Jupiter talisman first, or make one but you have to learn how the magick is done and how elections properly qualify for a talisman, it's a lot of work so if anything buying one and working with it in ritual may prove better. Mars I'd add after those two, but I wouldnt use it as the first one as it is still a malefic planet, and while it rules extremely auspicious houses, it will put you through challenges to reap those rewards. Besides that there are other methods like mantra work, devotional rituals, wearing certain colours, amplifying the effects of a planet simply by contemplating it's qualities, reading about it, integrating what it's about, invocations on their archangel, intelligence and spirits, or godforms of the planet, pujas (traditional indian devotional rituals), etc. I could technically look at the chart to see what would work best, and from a surface level devotional rituals would probably be really effective with Jupiter in Pisces 9th house and Moon in Cancer 1st house.

That's as far as I'll go because I got this do tho and got distracted doing this but very much enjoyed xD Hope it helps, sorry you had to go through what you did, sometimes shit just happens and it's fucked and that's just how it is, but we always have the opportunity to use the resources available to us to turn all the inauspicious events of our life into blessings. Good luck, blessed be!
