I used to have a few short heartache from last month and had a serious panic attack I never had in my life.
It felt like I'm having a heart attack. I'm about to collapse, faint. I poured down some water on my head. Took long breaths, tried to sleep but the panic didn't stopped. It came for about an hour where are ran frantically from here and there taking long breaths.
I don't have anything to be depressed about but just had such attack first time in my life.
It was scary and the only feeling I got was I don't want to die.
Do anybody have the similar attacks? What should I do if I had it next time?
Well you probably DO have something that's bothering you. Subconsciousness often speaks to us in this way. Try resolving your problems that you have for an extended period of time. That's very unhealthy and after some time it starts pushing you towards depression.
Deal with your problems as best as you can, don't run from them because sooner or later they'll catch you.
