How's your sobriety scared?
I can understand why you're obsessing over this but I think this is one of those cases where if there is nothing you can do about it then don't worry about it. You are getting tested and that is all you can do right now. I do think talking to a helpline will help you because they are trained to deal with situations just like this. They may be able to reassure you. The best thing you can do though is use this experience to move forwards...
