(((((( always )))))))
First let me say how very sorry I am for your loss. I'm sure it's heartbreaking for you and there is no wonder you are feeling anxious and upset.
Very often anxiety can feel like you are having a heart attack. Shortness of breath, light headedness, even pain in the chest area radiating to your arms are all common signs of an anxiety attack. BUT - you should be seen by either a doctor or a visit to the ER to rule out anything else it could possibly be.
We at PC cannot diagnose you.....please please, go to the ER with these symptoms and be tested to make sure there is nothing else going on with you medically. They can help you through the anxiety if that is indeed what it is and they can make sure your heart is in tact (physically of course).
I wish you well always.....please take good care of YOU!! Let us know how you are doing ok? And of course, welcome to PC!
