Depression can negatively affect your physical health. Gastrointestinal problems, like stomach pain, sleep disturbances, chronic joint pain, tiredness and appetite changes are all physical symptoms associated with depression.
I can understand your pain. I lost my mother to cancer. I was diagnosed with a rare form of brain cancer four years ago. Each member of my family and I suffered with some degree of depression as a result of my diagnosis.
It is important that you get intervention help. Meeting with a well-trained and sensitive counselor may be helpful. A support group of individuals who have lost a loved one to cancer may be another option.
Depression will not go away on its own. Please take care of your health.
