Welcome to the club

Usually it passes after a while unless you're in the midst of an episode. If you're not in an episode, sometimes you just have to wait it out while you see if you can find meds that help reduce the irritability. If you are in an episode, then you'll need to talk to your pdoc as soon as possible and find a solution fast.

Sorry you're going through this, but I can definitely relate. For example, I'm feeling especially pissed off today for no damn reason -- but as the saying goes: "s*** happens."
