Curses, Can you identify them or escape them? Options

If you think there is a curse on you, that is, something particular happens every time you do something, but that something particular is so extreme, inevitable and the end result so predictable, and it happens long in the period of your living, then can you say this is a curse?
Also can you identify a curse? Is it something real, or just in your head?
And finally, if you do have a curse, how can you lift it? Does the Lesser Banishing Ritual of the Pentagram help with this purpose?
Thanks

As everyone else stated. MANY ways to get rid of a curse. Once the intent is there it is just a means of channeling your will in a way where you "KNOW" the curse is broken. Whether this be sigil makings, incense burning, symbolic ritual.

As for finding the source of the curse. There are many methods. If you look into witchcraft they have some spells to bring things to light you can learn how to create a working framework in order to find the "source".
