The topic of suicide is also something that people want to explore as actors. As a writer, I've dealt with this topic as well, but not in an obvious way. I don't have characters shouting that they want to die and want to kill themselves. Instead, they are exploring the hurt and pain in their lives.
Here are some monologues and scenes for 1, 2 and 3 actors that explore the pain we struggle with that sometimes leads to an untimely death. But the scripts are not always hopeless. Some of the scripts may even provide some hope to those who are hurting.
