Hi, I just recently had chain of panic attacks or so I think. I seem to have all the symptoms of panic attacks but the chest pain I do not experience. I however have a much worst symptom and this is having my brain go completely dead on me. It feels like the entire world is caving in on me and nothing starts to make sense and I get really scared and confused. I was wondering what this could be because its been really scaring me lately. I'm also only 23 years old and I would expect panic attacks to happen in older people. Thanks Jeff
