1. You only live once?
You live every day.
You only die once.
2. If you aren't in the moment, you are either looking forward to uncertainty, or back to pain and regret.
3. If uncertainty is unacceptable to you, it turns into fear. If it is perfectly acceptable, it turns into increased aliveness, alertness, and creativity.
4. People who self-harm don't want to die. They are not trying to kill themselves, in fact they are trying to live with the pain. People who self-harm have a very high risk of suicide so they need to seek immediate attention and help.
