Seeing the people close to us or our friends struggling with mental health conditions can be hard. It is very important to know and acknowledge the struggles of the people we love and try to offer the support we can. Not many of us know how to support them and try to say the wrong things. The most important thing that one can do is to create a safe space for them without any judgments. It is sometimes better not to say anything than something that might trigger their condition.
