Hi..Thanks for the query. Can you tell me how is your sleep & appetite over last 15 days or so? when you tell that you are feeling depressed thus this mean that you feel sad/low all the time irrespective of events going as per your likings or desires & whether this feeling of sadness has persisted over last 2 weeks or so? Simply putting depressive episode or a syndromal diagnosis of depression in Psychiatry requires a minimum of 2 weeks period of persistent sadness, decreased energy levels, decreased self confidence/esteem which remain irrespective of positive/negative events. Additionally there are associated symptoms of sleep disturbances like sleep onset & maintenance difficulties or excessive sleepiness,disturbed appetite (under or over eating), disturbed sexual drive (libido) etc. If untreated these symptoms may progress to ideas of guilt, feelings of hopelessness, suicidal ideas & attempts. You mentioned that you had similar symptoms 3 years ago; so how long these symptoms lasted then? Did you take any medical help at that point for these symptoms? It will be a good idea to visit your primary care doctor once for a detailed evaluation. Good luck
