What you describe is a classic presentation of a panic attack.

You are not going to die tonight. Tomorrow, your doctor will help you.
This sounds like me 2 years ago,First of all your not going to die.You are having whai can feel you breathet is called a panic attack.A panic attack is brought on by fear,when your brain registers fear your adrenal glands release a massive amount of adrenaline.The adrenaline causes you to breathe deeper and your heart beat faster,but all you have to do is point out what is causing the fear and when you feel an attack coming just tell yourself its all in your mind and your body is doing what it naturally does when fear is present.
