Breathing and Anxiety?

Hey, do not take pills or medicine you have the same thing I had trough July 2010-October 2010 does it hurt to drink cold water too? you probably did something harmful to your throught and it makes it feel like you cant breathe because, well i really don't know how. I use to be able to control my own heart rate and breathing it was so bad, it also was due to the most stressful point in my life where i hated everything, and felt like i sucked, and such. It will pass but, if for some reason it doesn't i don't know what to tell you, if you want to try the pills go ahead i am not a doctor but yeah. I feel your pain
