Can't eat it makes me feel sick... And I've notice even when I can smell food I feel sick... Also I'm finding it deficult to breath too... Help me!?

STAY CALM. Well these can be symptoms of a lot of things so need more information. Are you pregnant possibly, or is this anxiety and fear about something. Take a deep breath and write down what happens and when and if anything makes it better or worse. Then go see your doctor.
