Hey sweetie,
I suffer from very mild asthma, which manifests itself, not so much in breathing difficulty but in kind of stabbing chest pains, that feel a little like someone has put a knife right in the centre of my chest.
I find it worse if I have been spending too much time sitting, and mine also appears to be seasonal - it is worse during hey fever season. Is it possible that it could be something like that?
If not, have you considered the possibility that it's a form of indigestion? Both of these are likely to be affected by anxiety, as anything that makes you tense up is likely to affect both your respiratory and digestive systems.
I don't see what harm spending some time doing relaxation would do, and you might also consider steam inhalation to ease the discomfort. In fact, I'm thinking a long hot soak in the bath might be good for you - most guys I know tend to shower rather than take a bath.
Finally, I've heard people swear by Bach's Rescue Remedy for anxiety. I've just started to use it, so it's a bit early to tell for me, but you could consider that too.
