Hi Finn,
I’m sorry to hear things haven’t gotten better for your mother. You have my deepest sympathies.
I’m going to re-direct you to the response I gave to the first question you asked on this topic:
While I’d love to say that there’s a risk-free cure-all spell, there really isn’t. However, if you want anything to try, you can try chanting mantras around her to lessen hers and your suffering and petitioning the gods if you wish. The point is, spells that take over the course of another person’s life are enormously risky and dangerous. It’s in the gods’ hands, like Littlefield said - you can pray, you can chant, but ultimately they get to decide.
May you find peace.
