I know all these feelings all too well. I am on the brink of losing my job, house and well being. I live alone with a fabulous dog and thought I was Superwoman. It all began waking up in the middle of the night with a full on punch in the air which left me breathless. Just a week ago, I had to call of work as I was hyperventilating. I went to the ER in order to find out I am having anxiety. Either heart issues or anxiety are no joking matters especially if you are alone....always call 911.
