This disease is really dangerous and may reach very complicated levels if it managed to control an entire human's heart. It raises doubts towards anybody and anything around. He becomes a trifling person and can difficultly trust anyone, however they're close to him or not.
From the most important reasons for generating this disease in people's hearts is that the evil side in human's psyche always beats the good side. And this is an expected result of inattention with heart and psyche and not refreshing them, which people should preserve it regularly as long as they're alive. From a time to another, a human should look at himself and at his deeds, and revise his thoughts and decisions in his latest couple of days. To see what wrongs did he do so he can learn from them and never do again, and also to know his good deeds to persist on them, and improve them as well. Thinking about whom did he insult or offend intentionally or even unintentionally. Whom did he aggrieve by a quick decision. Whom did he hurt with a reckless word while being in a bad mood. Whom doesn't he care about enough and those whom he is boycotting for no reasons or even for a known reason. Occasionally, you must look at yourself and evaluate it. And see whether you're improving yourself or walking in a wrong path and you're just not aware of it. Driving on 60 Km/Hr and wearing your seat-belt, or you're disregarding the radar and you have no side-mirrors in your car. From a period to another, you have to try to improve your psyche, manners, character and treatment with others around you. Self-discipline is from the most important steps to purify the heart and to, relatively, eliminate the evil side in it.
None of us would like to deal with that incredulous person who's always tense and cares about every little detail that would happen due the two upcoming days, and always afraid and not reassured with everything that goes around and just thinking about everything in details at the same time! These people are so pathetic. They always see everybody wicked and always expecting hatred from them, and thinking that all people are just living for their own benefits only, and also, most probably, may harm or deceive me. All mankind are bad. I always have to assume a definite and cautious first impression for all people before seeing or treating them, or even hearing about them. That impression includes that all the people has a bad hostile intent. For sure, people who follow this way in treating people are very tired and suffers a lot in their lives. The simplest disadvantage of this way of life is the permanent nervous confusion. And the huge number of thoughts in their minds that never let them sleep. And as soon as these thoughts come to an end, other thoughts start immediately. Over-thinking and worry leading to mistrusting people's intentions. Human's mind wasn't once created for this thoughts and nerves war. All their big problems and long arguments are just started with a simple misunderstanding. And the question is: Why?? Why do we do all of this?? Why do people exhaust themselves that bad??
Those people always feel arrogant and super-proud of themselves. And that repeating voice in their ears saying "You're the best in this world!", and all these people will never benefit you anyways. And "You can get and understand everyone. Nobody can deceive you, and you can deceive anyone."
Self-denial is the best therapy for this case. From time to time, you have to persuade yourself that you're not a better creature than other creatures in anything. And if you are in a great position, rich and own a lot of money, happy and relieved in your life, and some other people cannot find a piece of bread to eat, it's all just because of Allah's generosity and blessing for you. There's nothing that you've created nor planned for yourself. Even you, the whole of you, just came to this universe as a result of Allah's desire and munificence for your parents.
