Welcome Barbara
You will find many low carb friends here and you can decide how best to keep in touch with them...read through threads on the sub-forums of interest? start a journal?, join a buddy group? read the TDC? post in the general LC or Atkins sub-forums? whatever might help you the most. One suggestion would be to decide on a plan to follow, it's the #1 suggestion in Newbie Advice. http://forum.lowcarber.org/showthread.php?t=405273
In the beginning it helps to know your plan's "rules', the foods allowed, any limits on amounts, etc. The Atkins plan is right at top of that forum: http://forum.lowcarber.org/forumdisplay.php?f=98 or you can pick the lowest carb option of this plan: https://www.dietdoctor.com/low-carb
No need to feel alone, and there are threads about handling friends who are not LC because that problem does come up often.
All the best,
