Why should I see a doctor a therapist or a health worker if I feel suicidal
Non-treated depression is one of the main reasons of suicide. Even events that at first sight only bring happiness - like a new baby or getting a job - can become stressful enough to cause a depression. Postnatal depression (or post partum depression), for example, is quite common. Up to one of every 5 women suffer from it after having given birth - most of them without even realizing it.
Depression occurs because of an imbalance of chemicals in the brain. It is an illness. Therefore, you should never feel guilty for having a depression.
Basically, if you have been feeling suicidal for two weeks or longer, you probably have depression, and need to get treatment. Please make an appointment with a psychiatrist or physician and a therapist, so that you may be properly evaluated. Depression can be cured with a combination of mood-stabilizing medication and psychotherapy.
