I had many panic attacks, and it's completely normal to think you're having a heart attack when it happens. Actually that's what a panic attack is like for everyone, and I think it's great that you were able to recognize that it was a panic attack, because some people are hard to convince due to that "sense of doom" it enduces. A little side note, you should check your blood levels. Some deficiencies will make your nervous system ultra sensitive, and also make you feel depressed and anxious. Since you were feeling burned out for a while and now had a panic attack, it's quite possible that you could be dealing with something like a vitamin B9 deficiency. Just a heads up because sometimes people forget to check the physical factors when dealing with psychological problems, but the two very often go hand in hand.

Post. This is what it's for.
