Hi,
I’m not quite sure what else you might be seeking in terms of guidance…
Given my understanding of the situation, I had asked if you guys have considered seeking medical help/guidance. If yes, what has been diagnosed/suggested? If not done already, it might not be a bad idea for you guys to consider doing so, at your earliest convenience.
It would also make sense for your husband to consider seeking help/guidance from knowledgeable and experienced folk for Vedic/Dharmic remedies to address Pitru Dosha and propitiation of Rahu.
Take care…
