If so, then you may be dealing with stress. Let's face it, stress is a part of living. Many people actually perform better with stress, and it is not always a bad thing. Stress is an adaptive response that someone has to certain situations and can result from both good and bad times. Dealing with the birth of a child can be as stressful as experiencing the death of someone.
Marriage can be as stressful for someone as a divorce.
It all depends on how a person perceives the situation and how they deal with it emotionally. It's the uncontrollable stress that can lead to unhealthy behaviors such as alcohol and drug abuse. Relationships can be challenged by leading to verbal outbursts, and possibly physical violence. Listen to music. Make sure that it is the kind of music that you enjoy.
