Tracy - so sorry to hear about your ER visit. I hear your fear and frustration. It is hard to manage multiple medical issues and not get discouraged. I know every time I acquire something new I get a little mad then scared, and I then wonder if I caused it or could have prevented it.
Even if you if you find out that what's going on is related to ED, I hope instead of being angry with yourself (can't change what happened), you will be gentle and kind and take care of yourself. I believe in you. One baby step at a time.
One of my friends always tells her two year old, "being brave means being scared and doing it anyways". I think that speaks well to any kind of recovery.
