I am sorry for replying so late. My heart goes out to you. It's a hard situation. I happen to know one person who was "disfellowshipped" by Jehovah's Witnesses some time ago, and it was very tough because the family severed all communications. May God give you strength to persevere.
As for driving to church, yes, I know it's inconvenient, but I still think you should do it - maybe once a month or even once in a couple of months. My wife and I live in about 1 hr. and ~10-15 minutes from the place where our mission parish rents a chapel. A bit shorter than your trip, but still long, and we, too, wish it wasn't that long.
Get an Orthodox prayer book and just pray at home. On Saturday evenings and Sunday mornings, lit a few candles in front of icons, and say the litanies from the Divine Liturgy of St. John Chrysostom. It's OK for a layman to do so - we cannot pray the prayers that priests pray "mystically" in the altar area, but general supplications are OK for lay people to read aloud. Standing in front of the icons with burning candles next to you, and praying the litanies aloud will give you at least a bit of the atmosphere of the Vespers and Divine Liturgy. In addition, you can listen to Orthodox liturgical chants on your computer, because quite a lot of audiofiles are available online. Also, ask your priest to give you a book called "Hours," which contains many prayers that you can pray by yourself at home on various times of the day.
Welcome to the forum, and may God bless your journey to the Orthodox Church!
