We don’t really know.
There’s no consensus on the exact nature of depression and drug abuse.
Some scientists have argued that depression and addiction are more closely linked than other chronic illnesses, such as obesity and diabetes.
Others have argued drug abuse causes depression, or that depression is more often caused by other problems like stress and anxiety.
What we do know is that depression affects both people and animals.
We know that depression has been linked to a variety of diseases including cancer, chronic obstructive pulmonary disease (COPD), Alzheimer’s disease, diabetes, and heart disease.
Depression and addiction can also have profound effects on our health.
Depression can have long-term effects on the brain, and can cause cognitive and motor problems.
People who suffer from depression may also be at risk of suicide.
Many people suffer from anxiety, which can also be linked to depression.
There are also a number of other types of depression, which include post-traumatic stress disorder, major depressive disorder, post-partum depression, anxiety, obsessive-compulsive disorder, panic disorder, and substance use disorders.
Depression is a chronic condition that affects both the body and mind, and some people can experience symptoms that are associated with depression.
A common symptom of depression is a loss of interest in activities and relationships that have previously occupied them.
People with depression can also experience mood swings, which often include irritability, restlessness, insomnia, and loss of appetite.
A number of studies have found that depression can have a devastating impact on relationships.
People are often unable to cope with stressful events, and may become increasingly withdrawn from their loved ones.
Depression affects people who are young, white, and wealthy, as well as those who have health problems or are at higher risk of other health problems.
Researchers have found evidence that people with mental health problems are more likely to have depression, even after controlling for socioeconomic status and other factors.
Depression also affects women, people with lower socioeconomic status, and people of color.
Some researchers have speculated that the symptoms of depression are associated not only with depression but also with other mental health issues, such anxiety, and eating disorders.
Research also suggests that depression may be more common in men than women.
Depression has been shown to affect people in a variety “triad,” with some researchers claiming that the main difference is that women are more prone to depression and some research suggests that women also suffer from more anxiety disorders.
A few other research studies have shown that people who suffer depression have different symptoms, including increased mood, less interest in their work, and more difficulty with social interactions.
This may explain why it’s so difficult to diagnose depression in people with other health conditions.
But the underlying reasons for the connection remain unclear.
We do know that mental health disorders like depression, addiction, and mental illness are more common among people of certain races and ethnicities, particularly African Americans.
Researchers at the National Institute of Mental Health have found a connection between the stress hormone cortisol and the risk of depression among African Americans, and found that stress can affect the function of the brain.
In a study of more than 13,000 people in the United States, researchers found that those who had higher levels of cortisol in their blood had a higher risk for depression.
And in a study in Canada, researchers showed that people diagnosed with depression had higher cortisol levels in their brains than those who did not have depression.
The link between depression, stress, and depression is so well-established that there’s even a name for it: “stress-related psychosis.”
This is a mental illness that is characterized by a combination of feelings of sadness, anger, and helplessness that can lead to a range of symptoms.
For example, people who have been diagnosed with “stress related psychosis” have been shown by scientists to have lower levels of self-esteem, more depression symptoms, and less social skills than other people.
Researchers also found that when people with “psychosis” were given an antidepressant, the amount of time they spent in the “psychotic state” was correlated with their depressive symptoms.
Some of the symptoms that researchers have seen linked to “stress” include feeling “frustrated, isolated, hopeless,” and unable to feel compassion.
Researchers say that stress causes a range to mental health.
Stress can lead people to develop “depressive symptoms” that include feeling disconnected from others, experiencing increased anger, anxiety and anger toward others, and a loss in social skills.
Stress also can make it harder for people to function normally.
Stress causes feelings of worthlessness, which may make it difficult for people with chronic illnesses to function at their best.
Stress and depression can cause a wide range of health problems, including high blood pressure, diabetes and heart health.
These health problems can lead many people to seek treatment for depression and anxiety, even if they’re not at high risk of having other health issues.
Some people may find that the mental health and physical health of their loved one are closely related, or they may have an underlying
