high anxiety attack
It's very similar to an anxiety attack, only it's 10x worse. It happens when you use some sort of substance to alter the mind and have alot of stress come at you at once. If having a high anxiety attack, you may be able to feel the blood flow of your heart, alter reality slightly (not in the good way), have a heart attack, or even become unconscious. A high anxiety attack isn't life threatening, but what is is how you handle it. It lasts as long as 2 hours and is mandatory if already having one.
Oh my god guys, you will not believe what happened last night, I had a high anxiety attack. I thought I was going to die.
