Sorry to hear about your relapse. It sucks. I’ve been there. It is really discouraging 
This might be a signal to make some changes. For me I found my relapses happened because I built my “house” (sobriety) out of cards, with no foundation and no strength for the unexpected events of my life.
I reached out to an outpatient detox to start with, and after that I joined a twelve-step group, which I still attend. There is a list of groups here: Resources for our recovery
It is possible. It takes changes and learning but it is possible.
