Ah, you have my prayers.
I have been in very difficult times too, on varying lengths and for different reasons. I do know enough to know it can be spiritually tortuous. God be with you and have mercy on you.
I am reminded of some writings of St. Silhouan, which were a great encouragement to me when I began to read them. I don't know if they can help you. I'll look for a link to an article, and will post if I can find it. As I said, I don't know if you would respond the same though. Edit:
here is the article that talks about it. There are several books - especially Remember Your First Love by Archimandrite Zacharias.
It must be that much more difficult, being out of the Church.
Is there an Orthodox priest you could speak with, if you don't want to speak to a Catholic priest? I do not wish to discourage you, but I would not like for you to discover the truth at an inconvenient time - even if the Catholic Church allows you to receive the sacraments in an Orthodox Church, the canons of our Church do not generally permit it. This is a matter for discussion with a priest though.
The research would not take long with a good teacher. There are differences in how we look at things, but it is less than the gulf between Orthodox and some other groups.
If you like, come over to
TAW (The Eastern Orthodox forum), though some of our members come here to TT. We have Catholics there as well who chose to post with us, and we welcome them.

If you do come, it IS a fasting season for us so ... please be patient if we are not at our best.

But you are welcome, if the fellowship can help you.
You do have my prayers. God be with you.
