Dear Sir , How to face the situation of direct exposure to avoid repetitive behaviours and to overcome the catotrophising thoughts arising from those situations e.g. I have seen a frog in a bathroom and have made an assumption that it has gone through that part where there is no chance to pour water after doing urination and the same frog has also got touched with the bucket used for bathing. Sir, please help me to get relief from the thought that sprinkle of urine might have not contaminated the bucket used for bathing after getting touched from frog or ant.
