Cld b depression: Irritability can be a symptom of depression but it can accompany many illnesses as well--consult with your doc.

Stressed?: What you describe sounds like you are under stress and should feel better once its over. But if this is happening for a while and you see no apparent stress, you may be suffering from depression or anxiety. These are easy to treat, see your pcp.
