Welcome and there is a way out. You did it before and you can do it again. A relaspe is not forever.
A few questions:
Were you going to meetings or were you part of AA?, how many meetings weekly?, did you work the steps and how long ago?, do you have a sponsor, do you have a network of sober friends, do you have a connection to a higher power? I have found usually one of these is lacking.
Keep posting you will recieve the support you need.
