How can i get rid of my depression and suicidal thoughts?

Depression remedies: Include exercising, engaging in social interaction & engrossing activities, practicing gratitude, doing kind things for others, learning and practicing stress management, developing and committing to meaningful goals, avoiding negative thinking & negative comparisons with others, and talking to empathic & trusted people. If those aren't enough, talk to a mental health professional.

See a psychiatrist: If you are depressed to the extent of having suicidal thoughts you should not try to manage this without professional help. Seek psychiatric assistance.
