Can Anybody Tell Me An Authentic Spiritual Practitioner Who Can Help Me Out?

In these days , it is very difficult or almost impossible to find any spiritual practitioner throughout the World. Many people claim themselves to be authentic practitioners but their credibility is just like other professional faith healers.
Another important factor is that it is very difficult to guide people living in countries like Pakistan and India where such type of problems are common due to Hindu mythology. In Islam, supernatural things like JIN are present but they have their own world. The patients who say that they can see something like supernaturals, are not present in Saudi Arabia where Islam is very close to the actual religion. This problem is present more frequently in India, Pakistan and Bangladesh where all traditions and thoughts are influenced by Hinduism.
In medical, there is a condition called schizophrenia, in which affected person can hear or see many things which other don't. They believe that their mind is being controlled by someone. In my opinion you should visit leading psychiatrist of Islamabad for investigations. I also suggest you to say prayers five times a day which can make you free from such thoughts or things.
