Hey! I’m aware you’re a beginner with these things, or so it seems, but I am linking this ritual someone did for breaking a curse on their family, because even without utilizing deities, the bones of the ritual helped inform me a lot about how to break an energetic connection, using candles, intent, and ritual baths, to do so. To strengthen and protect yourself. Maybe it could also give you some ideas as well.
Of course, never summon deities you don’t research or have proper experience with before a ritual with them, which is why I’m just sharing for the basic idea they had. I wish you SO much luck and health in the future. Be well.
