Hi Brigit Faye,
Welcome to the forum! Distance does make the journey towards Orthodoxy more challenging, but not insurmountable. You've received some good advice in this thread. This is a thread
I started in a similar vein last year, which you may also find helpful.
Reading books or listening to podcasts about Orthodoxy is good, but can only take you so far. Orthodox Christianity is by nature a faith that is lived and nurtured in community. I would suggest, at the earliest possible opportunity, to make the trek to an Orthodox Church to worship with and meet others and talk with the priest. In this country, the Antiochian Churches are probably the best introduction for English-speaking inquirers, followed by the Greek Churches. Failing that, finding a priest, deacon or mature Orthodox Christian who is willing to work with you in your individual situation would be the next best thing.
As far as "weakening of your faith" if you can't attend an Orthodox Church or go to a Catholic one instead is concerned, that's probably more an individual pastoral concern rather than a doctrinal one. If you find that attending a Catholic church for now is feeding your faith and need for Christian community, I would hesitate recommending dropping it cold turkey before you are 'hooked in' to an Orthodox Church community and/or in contact with a helpful priest. In the early months of my journey into Orthodoxy, during the long stretches in between being able to get to the Orthodox Church, I found solace in attending an Anglican church liturgy and worshipping with others. In time, I found attending non-Orthodox churches left me feeling confused and spiritually empty, and stopped; but for a period, that Anglican church was a little oasis in the middle of a vast wilderness.
As far as the eucharist goes - you can't receive communion in the Orthodox Church until you are a baptised/chrismated Orthodox Christian. However, if you have been baptised into Roman Catholicism or another Christian faith tradition, you can still receive communion there until you become a catechumen in the Orthodox Church.
I hope that is of some help. All the best with your journey into Holy Orthodoxy and will be praying for you.
