Yes. Ive had them previously many times and went to the ER the first time - I had a collection of terrifying symptoms that made me think I was having a stroke.

You'll likely need to genuinely stop fearing the symptoms of having a panic attack to get rid of them. When you feel anything like that coming on work on knowing you really are ok and its simply your adrenaline / panic response out of control - do not try to stop it, you will just cause yourself more panic. Nothing bad will happen to you despite how awful and unbelievable they feel - go with the flow but yes they feel like death. Try to learn to enjoy them as crazy as that sounds - focus on how amazing it is that your body can do all that stuff just from an adrenaline response. I know that sounds odd but its a perverse backwards way of getting them to stop. Its the only path out that I know of.

(Also as a side note from talking to docs - despite absolutely feeling like you will pass out panic attacks do not actually cause one to pass out or lose their mind. I know it feels like that but let those concerns go when you have an attack.)
