Should a Person With Waswas Ignore Doubts About Impurity (Najāsah)?

If a person is suffering from waswas , should he / she also ignore the doubts he / she gets in his/her... Sorry for ex : if a person goes to the mall and recently touched a cat and gets a doubt that is there cat hair on my hands and checks and finds none and remembers he had touched some clothes and goes to durt them and back of hand touched the cloths and the person thinks , was there cat hair on the back of my hands . Or if a person is removing something from the road that might be harmful for street cats and while picking it falls off and touched her hand and in the middle asks herself that are you sure this was this this and gets the ans no , and then recalls what was she thinking while she was picking it up , and asks , was it that you were unsure if it was this this but still picked it up , and gets the ans most likely and asks any other than that -no . So she touches her bag and now thinks everything she touched is impure and all the people working with her , will get infection .if She cleans her bag and touches the chain of her and and thinks did I touched this part... Should these doubts be ignored too .
