Does anyone else get this:

i'll be somewhere, and get really excited about something... Which usually isn't too often, but when I do, it makes me feel like I can't catch my breath, and just like I need to sit down.... Then all of this scares me into a panic attack, and we all know how that goes... Also, does anyone get the feeling like your stomach is really full when you get panic attacks? Like you're just so scared that it won't go away?

Another questions is, does anyone just get random chest pains? They are not really bad, not so much as stabbing, just kind of dull pains... 99.9% of the time when i'm nervous or freaked out these happen... And it sure doesn't help when you're already stressed about about being scared of your health. My body is under stress 24/7, there is no letting up with me, either. I'm usually constantly twitching my foot and bouncing my leg up and down to control it...I have a feeling that most of this is stress-related due to the fact that this never happens in school... It's always as soon as I hit the door... It starts. I just come in, and instantly start feeling the feeling of scaredness, fatigue, feeling of impending doom that never leaves me, no matter where I go or what I do. I mean, could all of this be the cause of the random chest pains? I've done had an ekg, and of course, it was perfect. So nothing is wrong with my heart... What could be causing all of this? Can anyone please throw me out some suggestions of whether it's stress related or not... Thanks guys...
