Dear oneuser:

My advice, without going back and forth communicating with you, as you asked, and without “going back to the childhood memories and ‘heal’ something”-

you already know the daily schedule at work, the hi and hello and sitting together for lunch, things you mentioned. So my suggestion: when alone, at home, visualize those  situations, one at a time, and see  yourself in those situations, saying and doing what you  want  to say  and do, using a confident voice (you  can  practice talking out loud), your facial features relaxed and confident (you can  look at a  mirror, seeing yourself speaking to a co worker you are  imagining).

Prepare that way, alone,  in front of a mirror or sitting with eyes closed, relaxed, visualizing. Then at work practice what you visualized, not expecting  performance perfection, but progress. As you practice at work, repeat to yourself: “progress, not  perfection”.

And make progress, day in and day out.
