There is always another option and I suggest:
A cleansing spell/ritual followed by a protection spell/ritual. This will cleans you of the curse and protect you from further attacks from whoever sent the curse as long as you make those your focus.
If you do a divination before a return the curse spell, more often than not you will see that it will turn into a war between the sender and yourself. A divination isn't required before the cleansing and protection ritual, but is suggested to add confidence in your divination abilities.
Life is too short and precious to waste your time fighting. You would be much better off spending that time learning and growing, in my opinion. Cleansing and Protection spells and rituals are easily found spells or articles on this site.
