We don't recomend giving out any personal detail online to strangers. Yes we are all friends here and looking to help fellow Satanists. But there are infultrators, and we as Spiritual Satanists do have enemies. And they will use and abuse the personal information you just gave them to harras you non stop. So please do not give out personal information.
Also, if your mother isn't aware of you being a Satanist, and you don't want to be found out. Then it would be best to create your own account instead of useing her's and running the risk of her seeing this post/message and getting caught.
All the info you need is on the JoS. You don't need someone near by to help guide you on the path of Satanism. That is what the Gods are there for, and the groups are here to help if you have any questions. Satanism is a somewhat solitary path, we all must learn to rely on ourselves and not others.
