Evil eye is true. 
“And from the evil of the envier when he envies.” [113:5] 
Imam Ahmad and al-Tirmidhi  narrated that Asma bint ‘Umays said: 
“O Messenger of Allah, the children of J’afar have been afflicted by the evil eye, 
shall we recite ruqyah for them?” 
He said, “Yes, for if anything were to overtake the divine decree it would be the evil eye.”

In Islam, there is cures for this recommended by the sunnah of 
our beloved prophet Mohammad (peace be upon him). 
We are trying to revive the way of our prophet (peace be upon him).
 
NB: Listening to this is not a solution but a part of the solution.
