There are many ways to break a hex or curse, though you are correct that many hex or curse breakers are targeted for an individual you can use types of hex breakers which draw to power and negativity of the hex or curse at the object not towards you.
you can create something that is called a Witch Bottle which is usually a glass bottle which needs to have the ability to be sealed.
what you will need for the witch bottle.
- get a bottle which you can seal either by lid or cork
- nails or pins
- protective herbs such as basil, sage, white sage, holly leaves, holy thristle, vervain, bloodroot, buckthorn, broom (be careful with broom because it is poisonous), larch, mimosa. any of these will work as well as others with protective properities.
- if you do any sigil magick then you can always create a few for protection and curse breaking.
- salt (my preferance is Sea Salt)
- a black candle
- something that has your dna in it (most witch bottles use urine but you can use a lock of hair, some blood, nail clippings, spit etc.)
Put all the items you gather for the witch bottle into the glass bottle, (which will become your witch bottle) however leave the black candle out. Once all the items are in the bottle then seal the bottle with the lid or cork. Then burn the black candle and pour the melted wax over the opening on the bottle to seal it completely. once the wax has hardened go to a spot in your property and bury it in the ground and the negative energies from the curse or hex should be directed towards the witch bottle instead of your family. If you live in an apartment you can use bury it in a pot and have it stored in the apartment.
I hope everything works out for you :) if you have any other issues just send me a message and i may know a way of helping you if not i will try to find out for you. Good luck.
