20 wks preg and very hormonal, feeling out of control, what can I do to calm down?

I could go into a screaming fit or a crying session at any given moment. Right now my husband is sick, and because of him I am now suffering from a dull soar throat and ear ache and I am so mad at him that I am seeing red. When I hear him sniffle or cough I want to punch him in the face lol omg I am losing my mind!!! HELP
