Hii Lee,
I think you have to accept that relapse is part of the recovery process, it’s unfortunately likely to happen but it doesn’t mean you shouldn’t try again.
You did 6 months which is great, bet you didn’t think you could do that before? This time try and go longer, eventually you’ll reach a point where you won’t want to use again and undo all the hard work you’ve done.
There’s a life out there waiting for you to live it, you can do it! You deserve to live a life free of drugs and to be happy. Keep us posted on your progress.
