Use cognitive distancing.
Our mind usually worries about things it is convinced are true but, most of the time, are actually not true. You can balance your mind’s tendency to predict the worst outcome by coming up with positive alternative scenarios. For instance, your spouse seems distant and is sending out a lot of emails. You decide he must be having an affair. An alternative scenario: He is working extra hard on a project. Analyze what’s most likely to happen. Most of the time, the worst-case scenario your brain comes up with is not the most likely one.
