Irish, I am sooo sorry you are feeling so poorly. It's amazing to me that you have had "ESP" about dying and having it come out of the blue.
I, too, have felt that way. I knew in my '30's when I was still heathy and strong that I wouldn't live long. I told my Mom that and she asked why. It's just a feeling...just a feeling.
And lo and behold, I've escaped death several times. With the breast cancer, after the 4th chemo, I remember thinking....."this is what dying feels like." I told my husband and we dashed off to the ER. I was hospitalized for 3 days and put on steroids. I felt a lot better until they stopped sthe steroi and I experienced the "steroid crash." Oh, my. Another close call was when I had a reaction to IV phenergan. My husband saved my life as I was unconscious and not breathing well with a pulse oximeter of 56. They revived me, thank goodness.
And now I am battling these illnesses. But I KNOW about your feeling. I just know I'm not going to be here for much longer.
It's clearly just a feeling.... Sending you best wishes, e-chicken soup (I stole that from someone here), and good health asap!
