Not sure if this helps you, but some of us in my rehab group (including myself) relapsed and quickly came clean with the therapists and the group. My therapists called this a "recovery relapse."
Being honest with people about drinking/using again, and exploring why you did it and how to change it next time is what they look for people in recovery to do after a relapse. Lying about the relapse, hiding it, holding your feelings in, and continuing the behavior is the kind of relapse you do not want (and the kind I had many months ago that eventually landed me in rehab!).
I am proud of you for telling all of us. I hope you can talk to people in your life outside of SR to help you through it.
