Can't eliminate anxiety 100% but you can control it. This might sound crazy, but you need a "NEAR DEATH" incident.
Ever had a moment where something shocking occurred and you suddenly stop thinking? You probably had a face similar to this -->
I dare you to go outside and scream as loud as you can. Jump around, shake yourself off. Throw your hands up. Make stupid faces. Do this for 1-3 minutes until you are utterly wasted and have no energy left.
When you are done, listen to the sound of the unmanifested. Look around and you will see glimpses of life right before your eyes.
You've charged too much energy, negative emotions, anxiety, fear. Now its time to discharge it. LET IT ALL GO.
Humans must discharge. "What comes in, must come out"
When you drink, you charge. When you pee, you discharge.
When you eat, you charge. When you poop, you discharge.
When your angry, you charge. When you scream, you discharge.
When you sleep, you charge. When you exercise, you discharge.
When you have sex, you charge. When you have an orgasm, you discharge.
When you read, you charge. When you take action, you discharge.
When you charge, you must also discharge. If your not, you are DYING.
