Hi! My name is adria first: sorry for my bad english ;-)
I'm looking for magic help. In the normal way, it is not possible to heal my situation.
My family and I are in a very bad situation. We made a wrong decision last year. It should be a good thing, but it has changed our life terribly.
Is there a spell that alters our destiny or rewinds the spell to change our mind in the past?
Unfortunately, I can no longer see a way out.
Unfortunately there is no way to rewrite the past. However what you can do is magical work to change your current situation.
I'd start with some kind of divination (tarot, runes, whatever appeals to you) to determine what forces are negatively impacting on your life. If you don't do divination yourself find a reader with a really good reputation, there are lots of con artists.
After that I'd do cleansing work to remove the bad luck; this doesn't have to be complicated, you can make magical washes and soaps from anything citrus (lemon, lemongrass, citronella) and wash yourself and your home. You'll probably have to do this several times.
Along with removing the bad luck I'd do work to bring in good luck, you can make luck oil from cinnamon, vanilla and wintergreen oils. Anoint a orange candle with it and burn it with intent.
This is all a bit general as I don't know your exact circumstances. Feel free to message me if you'd like some more specific help.
But I need other help. I'm looking for someone who makes the impossible possible.
Something really bad happened to my family. We have made a wrong decision in the past that is dreadful to our present lives and prevents us from continuing our lifes.
Is there anyone here who can undo something?
I read about it. Or how to communicate a message / warning myself in the past.
It's not about money, saving a relationship or anything like that. It is a bit complicated...
Impossible to do. You cannot time travel back into the past and warn yourself about the current situation. It's best to accept what has happened and use this as a guide to learn from your family mistake to ensure that it won't happen again.
