Prevention Project Dunkelfeld (PPD) is a project to help people who are thinking about hurting themselves or hurting others. PPD helps people get help and get better so they can stay safe. People in the PPD project get help from mental health professionals and counselors. They give people advice and help them figure out how to cope with their feelings and thoughts. They also provide information about staying safe and where to get help if needed. The goal of the project is to help people who are at risk of harming themselves or others live a better life.
