Currently I am feeling a tightness in my chest area. Breathing is not short. I do not like this - i'm only 33.

I feel it could be stress catching up with me. I am a freelance commercial artist and for ten years it has been a neverending struggle for work. Hand to mouth, trying to stay optimistic; i'm tired of it. Life is passing me by, and I do feel a build up of psycho-emotional stress. No stability, no break. I already have some grey hair.

It could also be situational: my wife and I just had a baby, and it is overwhelmingly stressful. We're both irritated zombies.

But right now I also have a cold. Dry, sore throat, heavy nasal congestion.

If it's the cold, I can let it pass. On the other hand I don't want to have a spontaneous heart attack or something.

I fear a general doctor will say "take two and call me in the morning."

what should I do?
