People will ask for it, but not follow it. It’s best to let them talk about how they feel and, if time allows, give them a bit of your opinion. Don’t tell them what they need to do, you’ll only be wasting your time. People are going to do what they want to do. A good friend understands this and is there to lend an ear when needed. It doesn’t mean you have to endorse their every action, but do not attack them either. Support them when they need it, and let go when they don’t. Don’t cause yourself stress. I know it hurts to watch them hurting…but hang in there.
