UPDATE: That female co-worker apologized and said she overreacted. I'm sure the apology was sincere however I don't know how long before she strikes again. Reason being she became very chatty after that. During our conversation I could still sense underlying unsprung nervous tension. I noticed when a couple of my sentences were interrupted curtly and nervously. I don't know, I feel there is something about her that is not quite balanced.

How should I deal with this going forward?

Let me ask you all a question. If someone is addiced to pain medication such as Vicodin or Oxycotin, can this cause aggressive mood changes or psychotic episodes?
