I need some help concerning my experiencing a type of psychic attack

[Cannon]

I am regularly being attacked by a negative entity all throughout both day and night. I came to the conclusion that the use of affirmations may provide me some aid, but whenever I try them for a brief period of time the entity almost permanently forces the exact opposite meaning onto what I say, thus leading me to hurt myself instead of help every time I use one. For example, I would state something along the lines of "All of this in according to the One Infinite Creator's will" and I would instead feel that I had just said "All to the entity's will." I don't know how to undo this and would be very grateful for any advice on it at all, whatsoever.
