Like, for example, I'm so excited for this job interview, transforms into a wonder if they liked me and then moved into oh, I'm so stupid. I shouldn't have said that. I'm definitely not getting an offer. You start blaming yourself for things you didn't do and worrying about scenarios that may or may not happen. Overthinking is simply the act of thinking about something too much or far too long. I know the feeling and it's energy draining, right?
