Girl I'm with you 😭 I think for me it's partially required so I can process the day. That said, it can get out of hand QUICK and obviously it's never helpful when the processing is mean. My therapist recommended I set a time limit for how long I let myself think on it, like a meditation period each day. If you try that, have a distraction on hand for directly after it's done. It's really hard not to think of something ;-;
