i think yr doing all the right things and the advice here is good.
remember the benefits of being dragged off to church with your parents.
yes there are some!
you will get the chance to make lots of friends with protestants, and later on, you will be able to tell them all about orthodoxy. if u never hang out with protestants, you can't do that. how else will they hear if they don't have an orthodox friend?
also you can have a cup of tea before heading off to church (no fasting before communion for them) so enjoy that, soon sunday breakfasts will be a thing of the past!
also u can show yr parents u respect them and they can see your spiritual progress as you get closer to God through the orthodox Christians. maybe they will never acknowledge that but it will subconsciously make them think twice about what they believe.
if fact they are probably very insecure in their beliefs, maybe that is why they feel threatened by yours.
i still don't have any orthodox relatives, and i still have to face lots of difficult questions about why i am 'off the rails' and going to the wrong church.
don't worry, you eventually get used to it. focus on things you can enjoy together (i don't know, like fishing, listening to rap, going cycling or whatever, ideally not all 3 at the same time, or you'll just compose a funky song about how u drowned!) and make a point of being grateful for what they taught you.
i actually thanked my mum for giving birth to me recently. it felt really corny, but i wanted to acknowledge that she had suffered for my sake (i think this may be somewhere in the 'wisdom of sirach' deuterocanonical book).
about the finance side of things, i hope and pray God gives you that job soon so u can catch a bus. until then, is it safe in your area to hitch-hike? can u do some casual work to get a few dollars for the bus? u could try to go to a service that's not on sunday, so it doesn't cause so much hassle.
i spent about a year being a regular visitor at saturday services before i took the plunge and started regularly missing the sunday services in the other church i had been in. are u close enough to any orthodox churches to go by bicycle?
God will guide u. remember he has yr best interests at heart (hence the cross!) and also he cares about yr family and friends more than u ever could.
as our last coptic patriarch cyril (kyrillos) 6th said; 'be very, very assured, and leave it the hands of the one who holds all things in his hands'
also remember the pearl of great price is obtained at a price!
may God continue to give u peace and grace.
