The Sinking Feeling in Your Stomach

As soon as I know that I'm likely going to be leaving a job, dread starts to happen in the pit of my stomach. When you have a sinking feeling, you might feel something pressing down on your chest. Or when you're dreading something, you feel something in your stomach. It's an ominous, it's foreboding. And actually you used another phrase, sinking feeling. This is again what we would say when I'm pretty sure things are going wrong.
