Time does not cure real depression, only special medication. It's a disease. As a rule, a person does not realize that he is depressed. Perhaps what you call depression is actually longing or sadness. Find something to do or exercise and your boredom will go away.
Good day, if you have been diagnosed with depression, then you should have been prescribed medication and recommended to see a psychologist to find out the reason. If you yourself made this diagnosis yourself, then you can check how accurately you were able to determine your condition using the Beck test. In general, depression has pronounced symptoms: motor and mental retardation, negative mood, sleep disturbance, somatic manifestations in the body. If you pass the test and find out that you do not have depression, then your condition may well be caused by stress or trauma. PTSD is often confused with depression.
