Marywel, it is possible that this “psychic” may have cursed you with the very curse she “detected” and “predicted.”
I recommend to you the same advice I gave the OP:
About the prayer to break curses - often just saying it once is not enough. I would say it daily as long as you are experiencing “overwhelming oppression.” Generally people who are cursed or otherwise experiencing demonic harassment find relief with prayer and the Sacraments.
You will also need to renounce your involvement with the psychic. I assume you confessed this when you returned to the Church, but if you’ve never specifically mentioned your visit to the psychic in confession (and any other brushes with the occult), make a point to do so ASAP.
Here is a good prayer that both renounces the sin and addresses a possible curse:
Renunciation Of Satan and Claiming the Full Victory
