If you step in you might lose a friend, but if you don't do something to help out, your friend could get seriously hurt or even die. When a friend's problems include drug or Alcohol abuse, it's worth risking the friendship to save the life. But you also need to take care of yourself. Make sure you talk to someone you trust about your feelings and your friend’s problem. Your parents, a teacher, a guidance counselor, or another adult in your life can help you understand and sort out your personal feelings. If you don't feel comfortable talking to somebody you know, join a support group for friends and family of addicts. Again, know that you can make a huge difference by reaching out to help a friend, but that it ultimately is up to your friend to help him or herself succeed. Do not feel it is entirely your responsibility, or your fault, if things do not turn out as you hope.
