Hi Aurora, It’s been a pleasure to read your comments, full of sincerity and appreciation.
However — unlike what Shein mentioned — even though your Jewishness has not been proven yet, since your info. seems to indicate that you probably are, my humble opinion is that it would be kind of counter-productive to drive to a synagogue or to a Jewish family for a meal on Shabbos.
With the high holidays approaching I can only echo what others have said: find yourself a real life mentor. It’s a leap of faith you need to take, and even more difficult if you are shy, but it’s one that you hopefully will not regret.
