Showing support for another person may save their life.
It is better to #SaySomething than to not say anything.
If the person you are concerned about is unwilling to get support, please consider calling Student Mental Health Coordination Services at (805) 893-3030. They also have an online reporting form that you can access here. Student Mental Health Coordination Services will help you to figure out the next steps and they can reach out to the person you are concerned about.
