A curse can be removed by positive magic.
Jesus was the most famous positive magician. This unconditional love stuff is what protects you.
You can try it yourself or pray to positive beings to help you. You can also pray to God (he/she is a positive being).
But they only help you when you ask because of the free will.
You can send that love to you so that you have that protection. That is why Jesus said: " Love yourself as love others."
The curses are like programms that manifest in your body, mind and spirit. It doesnt matter if they are created by others or by yourself the technique to get rid of them is the same.
That is what Bardon says about what this programms are:
From Initiation into Hermetics.
Magic Psychic Training (VI).
The larvae form themselves involuntarily in the corresponding mental sphere as the result of a strong physical excitement, no matter whatkind of excitement this happens to be. The stronger the excitement is, the more mental material a person is subsiding, the larva will become all the stronger, denser and more viable,especially in the case of a regular and frequent repetition of the same physical excitement.This involuntary formation of larvae occurs in any human being, young or old, magically trained or not, regardless whether the person knows or ignores it. If the physical excitement is fading due to the fact that no attention has been paid to the upsetting affair, the larva too will disappear by and by until finally dissolving itself. Consequently there will be in the mentalsphere a constant bringing forth and dying of larvae, naturally at the cost of the mental matterof each human being. We are causing these events by our own psychic excitement. Thereasons can be very different, usually fear, grief, sorrow, fright, hatred and envy and such like producing them.
Many people are living under the erroneous supposition of being haunted and destroyed by blackmagicians, whereas they are in fact victims of their own fantasies, or putting it correctly,victims of the larva they have been creating themselves. People like this usually will not find out about this problem until they leave their mortal frame. Only a very few persons are actually haunted magically. Think of the numerous Inquisition victims of the past! No doubt there is a certain advantage for the average man in that the old order has changed, yielding to a new one, for “If a man’s belief is bad, it will not be changed by burning’. But one has thrown out the baby with the bath water without touching the roots of the matter and without verifying the higher laws.
The practice of unconditional love calms you down and helps you to get rid of those psychic excitements.
