The mental illness that we are going to focus on is depression. Depression is a condition that makes someone feel sad and hopeless most of the time, making them lose interest in things they enjoy. This can make them avoid socializing with friends and family, worsening their mood. Depression can also lead to drug abuse, which is the use of substances to get high and temporarily relieve stress. However, drug abuse has harmful effects on the body and mind, which in the long run, can create various problems. Depression can also increase the risk of suicide, which is when someone ends their life prematurely.
