Hello & thanks for the query. Short answer is yes you are suffering from
depression. Long answer is you are suffering from a chronic low grade depression known as
dysthymia where one tends to feel low, tired, non energetic most of the times but not to the extent that it would severely hamper a persons work performance. In addition stress from a non helpful relationship, job etc. usually adds up the woes of a dysthymic person causing an episode of
major depressive disorder superimposed on dysthymia known as double depression. Good news is this condition can be treated fairly easily by a multimodal treatment approach. There are drugs of SSRI group like escitalopram,
sertraline,
fluoxetine, paroxetine; one of which will be prescribed to you depending upon your clinical profile. Next up, a Psychiatrist or
Psychologist will take up with you lifestyle mofication; how to manage job & relationship stress, doing daily physical exercise to keep mental as well as physical health at a premium & ;lastly factors unique to your personality, environment & possible stressors to avoid to prevent a relapse will also be dealt with. Do
consult a Psychiatrist & if required; revert back to me for further help. Good Luck
