If someone you love has stopped doing the things they used to enjoy, sleeps too much or too little, and seems to have gone quiet inside, you already sense something is wrong. It might not be a rough patch. It could be depression.
Depression, also called Major Depressive Disorder (MDD), is one of the most common mental health conditions, and it often shows up alongside a substance use disorder. Left untreated, it touches every part of a person's life, their body, their relationships, their ability to get through an ordinary day.
Here is what depression actually looks like, what tends to cause it, and how to start searching for the right provider today. What families usually notice first is not sadness. It is a change in personality. Someone pulls back, loses motivation, stops answering the phone, or seems exhausted all the time. Some people start drinking or using drugs to quiet the pain, which raises their risk of addiction on top of everything else.
