Welcome dreamincolor....answers too all your questions id a definate YES!!!! I can relate to everything you have said. It can be very debilitating and terrifying. It causes my panic disorder, in which I take meds everyday for. I used to not eat thinking that if I had nothing in my stomach I couldn't V*. I learned differently when I was pregnant with my son, I felt better having something in my stomach. Youmay feel less n* if you have that one banana, or toast, or my personal favorite...I would eat pasta with nothing on it, so it's still bland as to not upset your stomach, but gives you some energy and calms the stomach.
You'll also notice that alot of people here have weight issues b/c of this reason. You don't eat and start to waste away. At my lowest I was 114lbs (I'm 5'9"), and was NOT healthy and looked horrible. Try to get some clories into you, you may be surprised to find you feel better.
Take care, and welcome!

PS...another thing I found in pregnancy - it's better to v* something (even water) than nothing at all, b/c THAT is painful!
That, which does not kill us, makes us stronger!
