we were in a tiny anglican church at the time. i kept on going, coz my orthodox church met on a saturday, due to not having our own building at that time (i also still went to the catholic church, which met just before the anglican one in the same building). we had been there 10 months, so knew many people and i wanted to keep in touch with them. plus my husband was protestant, so i wanted to accompany him to church, rather than make him feel he had just got divorced.
because i was attending both services, this drew a lot of attention, so when people asked if i was anglican or catholic, i would reply 'orthodox'
then i got to talk about orthodoxy and also about how important it is to have a regular prayer life and how useful it was to go to orthodox confession. i had lots of great conversations and i could see it made several people reevaluate their spiritual life, which is not a bad thing.
i expect i was also a bit hyperdox and full of excitement about my new church, which must have been quite annoying for some people!
had i not moved house, i expect i would have drifted away over a couple of years. there wasn't a sense of 'belonging' to the community and requiring 'release' like in some evangelical and baptist churches, so i didn't ask the anglican priest's permission. i did, however talk to him at length about orthodoxy (poor guy) and he seemed to be quite supportive (or just being polite and british)
for my extended family and friends, it was a different matter. they were mostly unimpressed, but i kept the lines of communication open as much as possible.
i know what you mean about accepting that things in the past were a 'farce'. but it could also be that you were worshiping God as best you could in ignorance and so don't be too hard on yourself. also God has mercy on anyone, not just Christians, so it may be easier to evaluate the past if you realise that perhaps some of your early experiences were instrumental in leading you to the true faith.
certainly don't try to follow 2 religions at once (leads to major confusion) but realise that virtues such as hope and love, which you may have experienced in your previous religion do all come from God. religions which are not Christianity may have corrupted ideas of hope and love, but that doesn't invalidate the hope and the love.
may God lead you and give you courage.
