I  had  gone  through  your  query . I  understand  your  concern .low mood  / longiness / loss of interest  in activities  etc may indicate  depression .If it persist  through  out day since 2 week then diagnosis  is confirmed  depression  acc. To DSM IV.You need proper  psychological  evaluation  and treatment .Depression  can be  treated  with  medicine  / psychotherapy  /behaviour  therapy  / ECT   choices  depend  upon clinical  presentation.Medicines  like  amitriptiline  /  SSRI  and  benzodiazapine  will  help to reduce  mood swings.In  SSRI  sertraline  /  escitalopram  /  peroxetine  will  help .Exercise  and  meditation  can  help .Ensure  proper  sleep  and  diet .I  hope  I  have  answered  your  concern .Feel  free  to  ask .Thank  you . </s>
