Hi,
Just because you go to church, prey an avoid anything to do with the accult, doesent mean that you have not been possessed or followed by a demoinc entity..
Many deeply religious individuals are most likely to be attacked from negative forces....for a classic example see the true story of Emily Rose (the exocism of Annalease Micheal)
Seek a spiritalist medium an ask if they sense any negative energies from you, if you are truly possessed, most mediums will freak out an ask u to leave.
If u feel you are possessed i strongly advise you to speak with a priest, coz if you are, or being followed by somthing negative only the church can help resolve the problem.
CPNs, mental health doctors will only make things worse as they dont believe in the possibility that demoic possession might be true, most dont believe in god or the devil and base their lives around logical thinking.
They will try to suppresse your thoughts and feelings through medication which in-turn will make it easier for what ever is attacking u.
