Depression

Depression often brings low mood, sadness, loss of interest, fatigue, tearfulness and feelings of worthlessness, along with unexplained anxiety and constant tension. Concentration, reading and speaking can become difficult, and sufferers may feel indifferent to things they once enjoyed.

Sleep problems, excessive guilt, negative thinking and physical aches in the limbs, neck, chest, stomach or back are common, and in some cases thoughts of suicide can occur.
