It's natural after a few days of being deprived of drugs or alcohol to feel anxious, remorseful, and want to start to fix everything. But there is a proper time and place for full disclosure of what we've been doing behind the backs of our loved ones.
As has been said here before, your amends and honesty will mean nothing if you are not able to recover from your addiction.
You need to find recovered addicts who can help you through this-- who can help you keep the focus on recovery.
Our experience is that it's nearly impossible to do this alone.
