TweetMaybe asthma? I don't know bro.
I have had a similar experience in my life where my body felt like it needed air and I'll be sucking it down, lungs will be expanding but despite the huge amounts of air I'll be sucking in - it feels like I'm not breathing. I've always assumed that is what asthma is like but it's only happened once.
If excitement would cause some kind of asthmatic reaction; your heart may be trying to compensate.
