I'm a newbie, half the time i dont know what im doing or trying something i learned in a book or online or even what I feel and come up with.
Friday, new moon, I made some little wishing jar earings, pair for each specific things I want.
1 for self love, 1 for money and luck, 1 for anxiety etc.

Lastly I made a pair of earings to keep away negative energy, rumors and thieves.
Wore one for luck, one for keep away negative and today my cute little lunch box was stolen from work T^T I think my jars backedfired on me.

What should I do to reverse it or start over?
First of all, not all bad luck is caused by curses, hexes or backfired spells. This is a very common condition and I have also gone though a phase when I had a streak of bad luck and I though "OMG! Am I cursed!?" (big spoiler, I wasn't). We are all humans after all and bad luck is just a part of our lives sometimes. I believe it exists to make us appreciate the good times or the luck that we have when we have it, everything has to be balanced (Would you know what light is if you only knew dark? How would you know what's good without anything bad?). And in case it WAS a curse (which is unlikely), could you share with us what is in the jars you wore on that day?
Thank you for the reply, I am currently on the floor at work right now so I can't think of the ingredients on top of my head until I go home and get on my notes.
The prosperity jar that I wore that day is the typical ingredients, cinnamon, basil, clove, and little green beads from my nail jewelry collection.
The keep away evil / negative is a little complex in my opinion, all I remember is adding salt, basil, I believe I added clove as well, and the last ingredient I added was he skin of a copperhead that my brother killed.
You see I had a betrayal a few days ago, a snake in the grass, and I was very bitter about it, very angry because it was from a friend, and I didn't want it to go through that so I felt it was proper to add snakeskin so I won't have any more snakes and thieves trying to Slither into my life.
@Nelly Did you cleanse the items before using them?
@Corvin yep, I always do.
Hmm, how about manifesting it back? This literally sounds like last Thursday when I wanted to make it rain so I made a rain incantation and it only got cloudy. Try this - on a paper write that u want ur lunchbox to come back Or u find it. Then fold it and burn it
