Wtf just happened

I just spent 9 'minutes or 20, shaking, feeling sick, saying "o god, imma fkin DIE, imma fkin DIE",my heart actually went to 150 beats per minute, my X ray came back (a week ago) and said I'm fine. No heart problems. If I get pain in my neck, arm, left arm, I think imma DIE. I have never experienced a panic attack like that, it felt like I was gonna die. I, still, shaking a little now. I feel sick, and feel like I will have a heart attack every DAY! I've never had a panic attack like this, this has scared the shit outta me. Has anyone ever experienced any of these?

Feeling sick
Mega racing heart
Feeling so weak feels like you'll die
Shaking and you can't control it for ages
Feeling like your gonna die
Feeling like you cannot breath but can

This is what happend During the attack! I am shaking now and can't stop. I just feel like Pire s--t.
It keeps stopping and coming back every minute sometimes. It won't F off... this is horrible...

Maybe the situation you were in when it first happened was really traumatic. Try seeing someone?
