Welcome to the forum.
I to am sorry to hear of the loss of your sister.
If you have been given the all clear from the ER then you can assume that these symptoms are down to anxiety. Have a look at our resources for some good links to self help sites on the web and keep posting here so we can help support you.
I try not to worry about the future -- so I take each day just one anxiety attack at a time.
