Loop it non stop until you feel relieved, it is much better (ime) if you do the actual tapping as well while telling yourself things to make you feel good, tap around the chest, and youll notice how the stuck energy starts to move around like looking for a way out, follow it and keep tapping wherever it moves to, when the stagnant energy moves it may feel like palpitations in the new place it moves to, or like a dull pain.
But also even if it does not move, tap around, chest, throat chakra, cheeks, forehead, crown, behind ears, plexus, shoulders, legs, belly… repeat.
Youll love it.
And here is the Primal Urge
Its a set but you can buy just the primal urge one, but the heart throbbing could help as well, becauss it really expands and breaks blockages around the whole area front and back releasing whatever fear or uneasiness.
I hope you feel better soon, also try to sleep a little elevated. Like double pillow.
