I didn't know what a panic attack was until I was watching a TV show describing one. At that moment I realized I've had them. It is a horrible feeling of desperation where you think you're dying. I had them at a moment in my life where I was really depressed. I remember not being able to sleep and crying while losing my breath and thinking I was asphyixiating to death. I felt really sad about the fact that I went throught that without anyone knowing what was going on with me. I didn't let anyone know how bad I felt. I would never wish this upon anyone.
