These are waswas and you must do all you can to fight them as they will eventually lead you far away from Islam. Perform Ruqyah on water and drink lots from it, recite your daily adhkar, make lot’s of du’a and ask Allah to help you and keep you rightly guided, and read the seerah of the Prophet sallAllahu alaihi wa salaam.

I am in a difficult situation where I feel restless all the time. I feel disinterested in things, hate noise be it someone delivering a sermon on loudspeaker or be someone talking. I like to remain aloof with most of time feeling sleepy. I feel I have lost interest in religious acts and feel my heart is hardened. Please help me come out of it. What has happened to me?
