Telling someone you self-harm can be very scary and difficult. Rehearsing some of the conversation can help you better get your message across when you tell your friend and give you confidence and empowerment. Practicing at home can also help you map out in your head what you are going to say and you can practice responses to potential reactions. Think about how your friend might react and come up with ways to respond. Face to face conversations are always harder but also permits you to get it out in real time.

Be sure to follow up the letter or email with a phone call or face to face conversation since the person you wrote may be very worried about you. Waiting to hear from you again can be very anxiety inducing for your friend. End the letter with a plan to call them in 2 days or to email you when they are ready to talk.

You will not have the benefit of non-verbal communication this way, so be cautious to avoid misinterpretations. If you are telling someone who lives very far away, they may feel powerless to help you. Try to suggest ways they can support you even at a distance. Calling a helpline is a solid way for you...
