I've been feeling stress for no obvious reason for the past couple of weeks. My muscles have felt jittery, shaky, and weak. Almost everything I eat has been causing intestinal problems.

Today I decided to try deep breathing. I made-up my own technique, but it seems to be "resistance breathing" ( 3 Deep Breathing Exercises to Reduce Anxiety | World of Psychology )

Surprisingly, the breathing took away that awful feeling of stress, dread, depression, and shakiness that has been almost non-stop for the last two weeks.

I've heard people talk about breathing exercises, but I was always skeptical. I'm convinced now. I plan to learn more about the proper techniques and practice every day if possible.
