Dear Tyler Sant:
Tell him you love him like a brother, that you wish so very much that he heals from his addiction, that you want to help him if and when he tries to heal from his addiction and whatever other pain he carries inside him. Tell him that every time you see him, every time he is there to hear you.
And don’t help him with anything except with healing his addiction.
Prepare yourself to the likely possibility that he will not seek healing for a long time, years, maybe never. You will have to accept this kind of pain yourself, knowing someone you love is “fading away” as you put it. This is YOUR pain and you need to take care of yourself for having your own pain over him.
