This (panic attacks) is an issue I'm struggling with currently. After a 7 absence they are back!!
What happened is, I quit smoking. About a week into quitting I started to get palpitations. They were scary enough and the result of a very long story is that three weeks after I quit, I resumed smoking. Just to get the anxiety (which all the websites assure me is normal) to stop. I didn't think it would be necessary to go to the doctor and request extra medication, I thought it's biological and the easiest thing to do would be to resume smoking.
How wrong I was. In the last three days I have filled three pages in my panic diary (It helps, I firmly believe this) and I'm economic when it comes to words. It's just one attack after another. And the medication we agreed on for the interim is almost finished.
It's still the hardest thing for me to convince my mind that what I'm thinking is happening is a lie.
