Hi biggirl
You'll find a lot of support here
Who you tell or not is up to you - perhaps you'd feel better coming clean and not living a lie anymore, but thats for you to decide a little further down the road. Staying sober is the focus now.
Of course, having said that, your health is pre-eminent - if you have the slightest worry or concern please see your Dr and don't worry about who knows - detox can be tricky for some of us. Please get help if you need it
