The technique is write down a specific upsetting events, describe the emotions you feel in response with percentages, point out any distortions in thinking (especially unhealthy thoughts) that may be exacerbating your mood, writing a healthier reframe, and writing your mood in percentages either. A simplified eversion would be to write down a specific upsetting event, identify any negative framing of the situation with writing, and reframing it in a healthier way (skipping the percentages).

how I feel about events helps track my emotional maturity (or lack there of).
“I’m so mad I didn’t get that promotion” reading that 10 years later shows how much entitlement I had.
now I’d write is more like “I feel sad that this happened, that’s okay, what can I do now”
additionally, I tend to rant in the journal in a way that’s just not acceptable to anyone as they may fear for my safety but in that ranting it shows kernels of truth of how I’m feeling.
it’s so hard to know how you feel because many? Most? Just cover up their own emotions.
you can also write something like “I hate X” then write out why. Then ask do I really hate x? Or is it and it almost always is a personal fault you have with yourself.
