nephi, i think yr feelings are normal for someone who has become orthodox.
my orthodox friends are from church and my work colleagues and family are not orthodox.
thank God i can occasionally go to weekday evening things, and i have a very understanding husband.
i would add one thing to the good suggestions here:
try to make good friends with the people who are not your age at church.
my best friends are either more than 15 years older than me or 10 - 15 years younger, and even when i was young i had plenty of friends who were middle aged or who were little kids.
maybe in your parish, there is even someone like me, looking for a young friend to hang out with!
ask them faith questions and cultural questions and find people who have similar interests and make time for them.
i have a friend in church who is (well, looks!) at least 70 and is not in the best of health. i love him a lot, like a kind of grandfather (although realistically i am the age of his children , not grandchildren!) he also seems very pleased to see me, like he is not used to hanging out with younger folk. he knows a lot about the history of the church in the roman empire and he is always bringing me tea. maybe you have a grandad waiting to get to know you, who is just a bit shy!
you don't have to have the same beliefs as your work friends. keep being friends with them, you may be the only orthodox Christian they know, and much later on, they may remember you and then start on their own journey of spiritual exploration.
also make friends with the saints. when you are studying the Bible and praying, also ask for their intercession and read stories of the saints. i always find this very encouraging when i am feeling like 'the only orthodox Christian' at home or among my work friends or in the extended family.
i just got used to repeating the usual defences and explaining again and again while i am 'still a Christian' etc. i think it gives me patience, and occasionally people are genuinely interested, which is a welcome relief.
may God give u plenty of friends, and may He help you also to be a good friend.
