Welcome kamalayka.
Do they use RCIA in that church?
I don't think so, but I don't know the Eastern process.
It is already mid-October. Is it too late in the year?
If you are already baptized, then it shouldn't be a problem. All you need is confession and confirmation. If not, then it may be, but I'm not sure.
I just want to add that I believe everything 100% that the Church teaches.
I don't know everything that Church teaches, but I know it is completely true.
You might want to mention this to a priest or whoever is in charge of taking in converts.
