I wonder if I'm the only forum member who actually believes in curses, individual and familial, intentional and unintentional, tended and untended. I know how to recognize them, how to perform them, and how to remove them, and I have done so for clients.
However--I have never told a client he or she was cursed; in every case, they have come to me with that feeling and asked if there was a remedy. And sometimes clients came to me certain that they were cursed, and I found they were not.
I personally would never charge more for this service than for any other somewhat time consuming and possibly hazardous energy work. My guides tell me how much to charge, and the most I've ever charged was US $125. I'm thinking that the last one I did for someone, I charged $90 for. Unless they can tell you why it will cost so much (which relates back to the "hazardous" thing), anyone who charges much above $250 is probably scamming you, as is anyone who tells you that you are cursed when you didn't ask.
Checking in, I do not feel that you are cursed, although I feel there is some past life energy with a negative thoughtform attached to it (such as, "I'll always be alone," or "Success always eludes me," or something like that) which probably affects one major area of your life and is kind of a bummer, but something that most people have in some area or other, and it wouldn't mess your life up near as much as an actual curse. But even if she were legit, this woman probably wouldn't be able do anything about that, if she wasn't tuned in enough to recognize it for what it was.
