I'm not exactly sure what you mean about "fuzzy feeling" but my stomach gets in knots when I'm anxious. I get light-headed, dizzy, tingly sensations all over my arms & legs, and my stomach turns over & over. When I'm distracted I don't feel it as much but as soon as I have down time I'm back to feeling weird. Is that similar to what you're feeling? I don't know what the solution for this is... I'm trying to find out myself.
