Dear Lybrate user. Mood swings and negative thoughts occur in every human being now and then. But if it lasts for a particular period of time and affects one's day-to-day life it becomes clinically significant. It should be diagnosed by a psychiatrist
we have a very good treatment options for depressive disorders. It is a three dimensional approach, treatments with medicines and psychological treatment with social skills training, by which one with depression
can lead a normal and productive life like anybody else. See a psychiatrist asap.
