Are minor impurities, with which a woman suffering from obsessive-compulsive disorder (waswas) in purity is afflicted, pardoned, and does impurity transfer to her from carpets and couches if she sits on them while wet?

We advise you to turn away from misgivings and not pay attention to them, for the default state of things is purity, and nothing is judged to be impure except with absolute certainty. You are permitted to adopt the view of those who consider a small amount of impurity forgivable, as long as you are afflicted with misgivings.
