Hi Tebo and welcome to Sober Recovery. I'm glad you found us.
Alanon meetings would probably be very helpful to you right now.
There are also Alanon and Naranon forums here at Sober Recovery.
Check them out, you will find a lot of people who understand what you're going through.
Post rehab is a very difficult time for the addict and their loved ones.
The best thing you can do is to seek out all the help and support that you can get for you.
