Being sad about your friend is not a warning sign of depression that may lead to suicide. While feelings of sadness can be a symptom of depression, it alone is not a definitive warning sign for suicide. However, it is important to note that ongoing sadness or depressive symptoms should not be ignored, as they can contribute to the development of depression and other mental health issues over time. It is crucial to seek professional help if experiencing persistent feelings of sadness or if concerned about one's mental well-being.
