Hey gingerwelsh- WELCOME!!!
You have found a great site for support, which can be a big help with your goals of sobriety. I was unclear if you also have an alcohol problem, but I did note the cocaine issue.
Perhaps if you were to 'come clean' with your family, you might find them to be supportive, which can help you in your goals. Again, I'm not exactly sure what those goals are, but I am assuming that you want to be sober. If so, that's a great thing.
If you're unaware, there's also another section of this site called; "Substance Abuse." You might that section helpful with the coke issues as well.

Again, doing something about your problem is a great step forward, and I do hope to see you around in here.
