My mom once went on a real bender for 9 months because someone insulted her at a party. She said the guy's comment upset her for the best part of a year so badly that she became ill and had to take extra drugs as a result. She also got upset recently when she was made to wait at a beauty salon, and again had to increase her drug dosage.
I have come to understand now why they are always upset and bothered about something. It provides the excuse they need.
