I had my first panic attack at the age of 15. I didn’t know it was at the time, but it hit me hard, and it took several weeks to get over it. It didn’t fit my idea of a panic attack. I didn’t have any difficulty breathing. I wasn’t shaking or running around screaming. I felt completely overwhelmed by doom. The only way I could describe it was that it felt like a near-death experience, as I became detached from life.
