Please answer! What will happen if I don't get help for my depression?

Nothing good. . Depression is a chronic, recurrent mental illness that affects one's ability to enjoy life, be social, be physically healthy. When severe, it can lead to suicidal thoughts. If left untreated, an episode of depression can last several months to a couple of years, and that's no way to life when help is available and effective. Hope you get it and feel better soon. Good luck.
