People who recognize characteristics of the Pissed Syndrome in a partner are faced with a difficult choice. They can continue to endure the episodes of fear and turmoil that keep them in a perpetual state of distress or try to get help privately. Here are some of the resources available for obtaining such help:

(For the fortunate person whose PISSED partner is healthy enough to be willing to participate in getting help - This may become possible after the abused person seeks help on their own first)
