Lisa,
Good for you for asking for help. Admitting we are powerless over the disease is the first step in returning to a healthy life. I know it is scary to tell your family, because I have been where you are. But, if there is anything that they can help you with, and I am betting there is, please humble yourself and tell them. There will be tears ( yours and theirs) but I know that they love you and want you to be with them for along time. Telling my family was the hardest thing I have ever done, and I wish I had trusted them sooner. Once the big secret was out, it felt like a huge boulder was lifted off of me. I had lied to them for so long that the shame and embarrassment became a way of life. I could start to like me again.
The other thing that is probably best is for you to detox with medical supervision. That means telling your doctor.
Please consider it.
Dawn
