Is a person considered to be suffering from waswas (obsessive doubts/thoughts) if they feel fear and anxiety regarding some of their actions, such as the fear of diseases or sins?

Natural fear of diseases is normal, but if it exceeds the limit and dominates one's thoughts, then it is from the whispers of Satan. Likewise, with the fear of sins: natural fear of falling into them or of their consequences is religiously مطلوب [required/desirable].
