There are people who can help, who want to hear what you and your friend have to say. Self-harming is destructive and stops people dealing with their pain. There are better ways to deal with the way you feel, and the first step is to reach out and talk to someone and see the future you have ahead.
I had this put on my husband's headstone. I received a card when I was trying to design it, and i knew it would be perfect. Unless you've been there you don't understand. Pray that you never do. Our first holidays without him. People say, "but you wouldn't want him back like that." Truthfully, yes I would. To care for him again, to have him here with us.....Sadness in trying to carry on, but knowing you are less without him. Missing you so much right now.
