For the past hour or so I've been feeling lightheaded/spaced out, the only way I can explain it is it feels sort of like I've been blowing up balloons, I'm terrified that I will faint although I've never fainted in my life (touch wood). I seem to fixate on my breathing and although I dont think I'm hyperventilating (I'm not gasping for air) could that be the cause? Can shallow breathing make you faint? What can I do to make it go away?
Thanks!
