I would summon or petition Pazuzu, Murmur, or Belial. With the request to remove all curses, hexing, crossing, bindings, freezings or other malevolent spiritual spells that (might) are placed on you.
(and ask if they/him can do that as fast as possible)
Here you can find a thread about how to do a petition that brother @darkestknight wrote.
Second step…, (basically additional banishing, I would use the two rites from these two books, first the 5 day rite when that is complete the 3 day rite)
This entire thread can have interesting information.
@HelixArc and @Dankquanicus had great results with these two books.
Angelic Protection Magick, by Ben Woodcroft
Magickal Protection’ by Damon Brand.
Third step…, (again optional) search the forum for a good uncrossing rite.
Fourth step…, (optional) In this thread @Enchantingstar disscucces the metaphysical properties of black copal which could potentially be interesting for you to delve into.
Fifth step…, (optional)
You could watch these videos in which a magician (a author at BALG.co) preforms multiple banishing rites unto the viewer.
Edited version of those three videos for a smoother operation. (especially when the video is looped/repeated)
Good luck
