Laughing > Dizziness, chest pains, not being able to breathe properly.?

I'm 18 years of age, I'm female. Whenever I laugh, I get really dizzy which comes with chest pains and not being able to breathe properly. I end up sitting down with my face in my hands, and seeing white spots from it all. It feels like something is leaking in my chest too, which doesn't feel too normal. :/

I'm not really so fond of doctors, so I decided to check online to see if someone has had anything like this before, and know what it might be..

Thanks anyway. x

And no, it's not really anything to do with laughter being good.

I've never had this before.

There's a fluttery feeling in my chest

It feels like something is leaking :S

It's so sore, I can't breathe properly after it.
