Every few months or so I have days when I get a feeling of dread for no reason at all. It sort of feels like I'm anticipating something really bad is about to happen, but never does. It's quite a scary feeling, and I can feel it too like growing from the pit of my stomach upwards, but only lasts about 30 seconds. Sometimes I can have it a few times a day but then I can go months without it. Does anyone have the same? I think maybe its stressed related but my friend thinks I should see my GP incase it is something else.
