Relapse happens to many people in recovery. It does not erase the progress you made. Like diabetes or high blood pressure, addiction can flare when conditions shift. A return to use is a signal, not a sentence. It points to something the treatment plan missed. Maybe a trigger went unaddressed. Maybe support thinned out. What you do in the next day or two matters most. Reach out. Get honest about what changed. You can regroup and keep moving forward.
