Assalam o Alikum.. . I experience severe waswas for months but sometimes it gets better and sometimes it gets very bad Like for about 2 months I was at peace.. I didn't get waswas that bad. But now for the past few days.. I am getting severe ones.. Like sometimes i get a terrible waswas but I just change my face expressions like movement of eye brows aur anything and i feel like I've done shirk. When ever I talk about an issue i get a thought that a particular thing is mentioned in the Quran but i immediately realize that the thing isn't mentioned so i feel like ive to done kufr again by adding something to the religion.. But I don't speak anything at all.. I can't even smile fully because im bombarded with waswas telling me that im smiling at those waswas even though i don't smile at these thoughts. Sometimes i feel like I've done kufr but i really forget what actually happened that made me think that I've done kufr. Also when i make dua.. I say Ya Allah.. and other names start coming to my mind.. I feel like i am making dua to somebody else.. Astagfirullah.. But i know that Islam is the true religion. I am so upset.. I get a kufr or shirk thought and i feel like I've done something that took me out of the pale of Islam then i keep on recalling what actually happened and what my intention was. I am extremely upset. I dont want to die as a kafir. Please advise me what to do.. One more thing that really concerns me that.. I again felt like i had done something if shirk so I was making dua to Allah to forgive me.. Suddenly a thought came to my mind that I am making dua to Holy Prophet S.A.W. and i even think that I did make dua to Holy Prophet S.A.W unintentionally all under the pressure of waswas.. The moment i realized what had happened I just started crying that I've done shirk. i know Allah is the only lord. i am not sure if I've done shirk or not. I felt like i made dua to Prophet S.A.W but it was unknowingly.. it wasn't deliberate. Advise me please
