(((((((hugs)))))))

I wish I had more advice to give. All I can say is be there to l isten if they need it, or if you arn't capable of giving them much support due to triggers give them references to people who have helped you. You could give them helpful sites with suggestions of other coping skills. Mainly you know the truth, chances are they won't quit or seriously try to until they are scared of cutting/themselves. And even then, once it gets that far, they will have to be completely determined that they want to quit more than almost anything else. That is one of the hardest things about SI, you don't try to quit until your so far down that it is almost imppossible.

I wish you the best of luck and please try to keep yourself safe. It is really easy to let ourselves be triggered in our attempts to help others.
