Hi ColombianJew,
I did take the time to read your post. What question are you posing specifically to the CR? None of us here would have as much knowledge about your case as the people you have already asked.
Are you a practicing Orthodox Jew currently? I know there are a lot of difficult emotions involved with this, but if I were in your shoes, I would ask myself if I were comfortable with my status being uncertain in many places. I personally would not be comfortable with that, and would probably ask the CRC something similar to:
Worst case scenario, both my mother’s and my conversions were invalid, and I am not halachically Jewish, although for most of my life I believed I was Jewish. I consider myself an Orthodox Jew, and fully intend to keep the mitzvos and serve Hashem. What is the best way to resolve this? Would this course of action change if those previous conversions were potentially valid?
