Why do you want it deleted A?
If the account is somehow causing you problems, maybe say what they are so people can help you resolve them. If it's because someone at home has seen you on here and knows your user name for example, you can change the user name easily. Maybe you would prefer not to be getting email notifications and that's easily sorted as well.
If you are feeling a little shame-faced about your slip, please don't. You are in such early days, and we all struggle at first. In fact we can learn a lot from our slips, and as long as we are willing to use what we learn, then that can protect us from future slips.
I hope you will decide to stay, and that you will continue your journey, through sobriety, to recovery.
