Hi, in the past few months I have noticed symptoms that correspond with symptoms of panic attacks. It usually happens when I'm in class or driving or somewhere I can't easily leave. I start to feel really out of it and lose my sense of reality, I get tingling feelings, I get really hot and then really cold, ears ringing, dry mouth, my hands get clammy, I feel like I'm going to pass out or have a seizure and I start to panic. Usually I can calm myself down by putting my head down in my hands but sometimes I have to leave wherever I am. I'm 20 years old and this has been happening since Oct. of 2007, usually at least once a week. Is this a panic attack or could it be something else?
