Firstly, many years and God bless you!
You have many options, I will narrow them down to these two!
First one is totally ridiculous, nevertheless, its a good joke:
Stay in the RCC, become a priest, then bishop, the archbishop, and then Pope. And when you are the Pope, come out of the window (after they say habbemus papam) and say:
I am an Orthodox tra-la laa... (I just want to see everybody's faces) LOL
Now, seriously. PRAY! A lot. And PRAY some more! And then... PRAY! God would not bring you into the situation if He didn't have the plan (He always has a plan).
Then, the avenue will become obvious.
It most likely will be to come open and tell everyone how you feel.
It is, also, very important to become an Orthodox only if you really believe that Orthodoxy is Orthodoxy.
Running away from something is not a very good idea. I am not saying that you are, I am just saying that you need to be fully sure that either way is THE WAY.
So, pray. He knows what to do.
In whatever you do, do not ever think that you are alone. We are, none of us, ever alone. So, have faith and you will get according to it.
I would also suggest to talk with priests. Tell them what is going on. That is their job!
So, do not worry nor be freaked out... it is all good.
"All systems reporting nominal activity!"
Pray and you will get what you need to do. Talk to people and when everything is clearer, make a decision, praying always.
Also, this forum is always here... so... keep asking... keep digging and to quote good old St. Paul: "everything comes to good, to those who believe in Christ Jesus".
