How does the lack of feedback in digital rejection change the way a person processes their own self-worth?

So I haven’t read the details yet but in my experience lack of feedback when responding to digital content removes the “sounding board” that typically accompanies in person conversation, aka thinking and planning a response. In today’s world of instant 5 second responses patience and organization have suffered most.
Now the details.
Drafting a letter or simply writing one’s feelings of discontent is an effective strategy in processing working through and often tempering one’s emotional response to any situation.
I’m a man I find writing helpful I have a therapist I’ve seen for years usually twice a month and I sometimes talk to my brothers dogs; I know they cannot respond nor understand but it helps.
Suppressing feelings leads to poor decision making. I had had a drinking problem. Got help ( not from the dogs) in general we all need an outlet to let off some steam and talk things out (process things).
I’m not sure what you mean by “soft energy” but I’ve always found preparation, a good sense of humor ( ideally an appropriate one), as well as a consistent smile (even when forced) ameliorates most everything.
