I'm having random dizzy spells. If I were to bend down to pick something up, im unbalanced and feel swaying side to side. Fatigue and lack of sleep?

Positional vertigo. When dizzy spells occur that give the sense of swaying or motion, and when they are worse with moving, this is usually a sign of benign paroxysmal positional vertigo. This is not caused by lack of sleep or fatigue but rather by changes within the inner ear.
