Do the whispers I experience in my prayer and when I sit alone, and those useless thoughts, and the feeling of someone speaking inside me, and the desire to cry, indicate the presence of jinn possession (mass) or the evil eye ('ayn)?

Treating obsessions involves seeking refuge in Allah and supplicating to Him, striving against the self by repelling them and not surrendering to them, occupying the self with thoughts of what is beneficial, seeking refuge in Allah from Satan and spitting to the left three times when feeling intrusive thoughts during prayer, and filling leisure time by learning beneficial knowledge and associating with people of piety and righteousness. If the obsessions increase and persist to the point of illness, one may consult a trusted doctor.
