It definitely sounds like anxiety. Tingling or numbing of hands and arms/feet and legs, dizzyness, nausea.. It really sounds exactly like anxiety. I used to think I had blood pressure issues because my anxiety would make me dizzy pretty much around the clock, even when I didn't feel particularly anxious. Just try and identify what your anxiety feels like and try to always assume that it's anxiety, because in 99,9% of cases it is. Even if it feels different and new, it's pretty much always anxiety
