You can check out both Emotional Self-Defense[1] and emōkō[2], for some theory and drills to practice dealing with emotional attacks. One of the main principles is what I call the three steps: 1) truth, 2) fair play, and 3) love. Or telling the truth about how I feel, telling the other person how I imagine they might feel, and saying one thing to connect to them with love.
The emōkō site has quite a few audio reflection drills I created to practice these three steps, with a variety of emotions and contexts.
Lastly, checking out my podcast, The Jim Kleiber Show[3], especially the segment the DailyJim, where I do 5-10 min reflections most weeks Mon-Thu about a lot of these topics.
I want to better organize these tips and tools I've built, as I have a lot more, but that's what I have for now.
If you want to talk more about this, please reach out to the email in my bio, id love to share more.
