I agree with Xusk. Also, just generally speaking, I think it's better and you can get more out of rehab if you go by your own will rather than going because you got to the point of being made to go. Like, it's better to seek medical treatment about something going wrong in your body right when you know something might be wrong, rather than waiting until you NEED to go.
So, if you honestly think rehab will help you again, and that's what you want to do, I think you'll get more out of it by going before it gets to the point of you maybe getting out of control enough to where you're being made to go back. Better to take care of stuff early. But, also better to not get into stuff that's hard to clean up in the first place. I'm sure you know what you need to be doing, so keep it as a goal and work towards it.
