I'm kaseer us shak in waswas and my life is miserable due to taharat najasat waswas. I'm trying to ignore doubts but unable to do it. Not understanding what to do to get rid of this disease.

Please recite as much as you can salwat and istighfar, inna anazalna, qulhuwalalah
while walking, driving, during journeys, while on bed and gift to imam e zamana. And always keep this hadees in mind that imam Sadiq Alayhissalam has declared the waswasee person under shaytaan reign. Also fasting in the month of shabaan can eliminate this waswas issue
