Welcome jfred!
You'll find a lot of support here on SR.
First things first - withdrawls & reducing associated anxiety.
We can't give medical advice, but we are here, have been through this, and will be here for you. Talk to us about what's going on. What are you afraid might happen? Do you know what medical facility you will call if you start to have issues?
Relapsing, if used as a point of learning, can often be a wake-up call that enhances sobriety. It's an opportunity to reflect on what wasn't working and make some adjustments. This is a step in your recovery journey to take it to the next level if you choose to view it that way.
The only way forward is threw (through? - I can't spell), step by step.
