Contrary to what many people believe, depression is a physical illness as well as an emotional one. Individuals suffering from the disease may complain about headaches, chest pain, muscle aches, back pain, and an upset stomach.
Approximately 350 million people suffer from depression worldwide. Many of them will experience anxiety, mood changes, difficulty concentrating, changing in their sleep patterns, and unexplained aches and pains.
There is no single cause of depression - hormones, brain chemistry and genetics all play a role, according to healthline.com. Individuals who suffer from low self-esteem, abuse alcohol or drugs, or have a family history of depression are at a higher risk.
The good news is that you don’t have to suffer forever. You can treat clinical depression with psychological counseling and antidepressant medication.
