 And the thing you need to remember in that scenario is your power as a loved one of this individual. You have to remember that actually you hold the most power to be able to bring this person back. Now, I say that with a bit of caution because you also have to ensure that you don't bear the burden alone and that you don't take it on your own shoulders alone to change this person's path. Make sure that you are surrounded by a community who supports you and you can rely on.
