Often, I'll feel that everything around me is not real. I'll just be working on something, spacing out, or even listening to someone talk and then suddenly its like my heart beats faster and its gets a little harder to breath, but not to the point where i'm panicking. It normally starts with this one question in my head which is "Where am I?" I'll feel really detached from my body and everything'll be really foggy and numb. Kinda like i'm watching my life through a movie screen. This will for last for hours and happens almost everyday. It makes it extremely hard to concentrate and its really affecting my ability to pay attention in school. Does anyone know how I can deal with this and what to do when it happens?
