Yes and no.
A "gypsy-curse" is simply a stylised form of focussed intent with the aim of manifesting harm in the form of some unwanted outcome.
Since it is clearly a free-will infringement to do such things (unless you for some reason agreed!) then it is a dangerous thing to attempt. A positively polarised (service to others oriented) person would never do this. The Gypsy is responsible and ultimately karmically accountable for thier actions.
If you believe in the power of a curse, then you yourself are unwittingly adding to its power since you are focussing on the outcome of the curse.
The fact that you even ask the question means that you have some doubts and therefore have in someway been subconciously been affected by this - which means the curse has had some effect.
Swanny, this is a learning opportunity.
