I hope that your friend makes it back. I really do. But whether your friend makes it back or not, you really don't have any control over what that person chooses to do. The best thing that you can do to support that person is to work on yourself because you are the only one that you have control over.
Let's be realistic about this. When people are out they're in active addiction sometimes they don't make it back. I know we don't want to think about this but I have seen it many many times. You want to be prepared in case that happens because you don't want to find yourself following in that person's footsteps. So now is the time to get active and keep your head on straight.
Whatever you do, don't believe the lie that it's okay to drink. Play the scene all the way forward. What happens if you take a drink or whatever it is that you do? You might feel good for a very short time but in the end you will be right back where you are right now and you will have to start all over again and you will have accomplished nothing.
The big lie that our disease tells us is that this time, everything will be okay. But it never is is it?
I think I'm the preacher on here that nobody ever pays attention to. I'll tell you the same thing that I tell everyone else. The best thing you can do is start getting to meetings and forget about relationships for now. I'm 63 and I've been happily married for over 3 years now to a woman who I've been in a relationship with since 2015.
So between 2002 and 2015 I stayed by myself and learned who I was and how to live life outside of any relationship. I'm doing very well. Most people are not very fond of that suggestion but I'm here to tell you that it really does work.
Seek people that have been sober for a long time and stick close to them. Get yourself a sponsor and start going through the steps and you will come out a new person with a brand new attitude and taste for the good side of life.
Don't worry if these people that you seek out don't have anything in common with you or don't look like you or they're not the same age as you. That's not why you're seeking them. You want sobriety and that's what they have.
