Reaction formation may be a temporary coping mechanism, but it’s unproductive in the long run. It ignores underlying beliefs or challenges that need to be addressed, which can hurt mental health.

All chemical reactions involve an energy change. We categorise reactions by the direction of this energy change. If energy is released by a reaction, the reaction is exothermic. If energy is absorbed ...
