Hi,
There are a number of afflictions in your birth-chart. So, it does not make much sense for you to lose sleep over Mars/Kuja being placed in the 8th house and aspecting the 2nd house of Family Expansion or a bit of a toned down version of Mangal Dosha.
I’d actually suggest that you consider validating the strong indication of Pitru-Dosha (something that would impact multiple facets of your life – including but not limited to health, education, marriage/children, career/growth/progression, peace of mind etc.) and seek help from knowledgeable and experienced folk for suitable or appropriate Vedic/Dharmic remedies to address the same.
Pitru Dosha is supposedly associated with karmic debt of one’s ancestors, involving their past misdeeds, an indication of unsettled souls, or wrong actions in their lives. Please consider a quick/simple Google search, to get a better understanding of Pitru Dosha. In my understanding (as called out earlier), this will affect multiple facets of the native’s life – including marriage/children, quality of and success in life, career growth/progression, accomplishments etc. So, you would be better off addressing the same with appropriate Vedic/Dharmic remedial measures, on priority basis.
In general, association of Rahu with Sun/Ravi, the 9th lord/house etc., is considered to be an indication of Pitru Dosha. There are different schools of thought on this, as with other topics. In your case, the conjunction of 9th lord Sun/Ravi who is placed in his Neecha-Sthna or sign of debilitation with Rahu calls for validation of the said Dosha…
Thereafter, it would help for you to be aware of the Moon/Chandra in your birth-chart being adrift in the middle of nowhere, with little or limited support on either side, making your mind/imagination run wild aimlessly. In all probability you seem to be somebody who is a bit of a loner with limited social life and fewer friends. You are somebody who thinks you know everything, does not need help or guidance…you seldom seek advise and very rarely (if ever) heed to such advises. You might also be stubborn, inflexible and have rigid thoughts/mindset.
There is also the possibility of you being around ill-wishing, ill-meaning, jealous and envious folk (for whatever reasons), who might be casting evil eyes… not to mention you might be susceptible to Black Magic and other such evil spells.
Take care…
