You’re right. When we get our mind tangled up in negative thoughts, we might need a way to take things less personally at times. Here’s an interesting word that I think helps us flow through life with less anxiety in and after our interactions with people:

Sonder - The profound feeling of realizing that everyone, including strangers passing in the street, has a life as complex as one's own, which they are constantly living despite one's personal lack of awareness of it.

Knowing that there’s an equally complicated life happening on the other side of side of every communication in life helps us to flow onward more peacefully. 

Just what came to mind. Have a great day!
