 Depression and anxiety
They are different disorders , but they commonly occur together. They also have the  same treatments.

Severe or ongoing feelings of depression and anxiety can be a sign of an underlying mental health disorder.

Anxiety may occur as a symptom of clinical (major) depression. It's also common to have depression that's triggered by an anxiety disorder, such as generalized anxiety disorder, panic disorder or separation anxiety disorder. Many people have a diagnosis of both an anxiety disorder and clinical depression.
Treatment

Symptoms of both conditions usually improve with
Psychological counseling (psychotherapy)
Medications, such as antidepressants, or both
Lifestyle changes, such as improving sleep habits, increasing social support, using stress-reduction techniques or getting regular exercise, also may help
If you have either condition, avoid alcohol, smoking and recreational drugs. They can make both conditions worse and interfere with treatment
