I can relate, I also am that quiet stoic anime girl who's actually lonely but doesn't want to admit it.
At least go to Liturgy, my man. You don't need to be fully active in community if university sucks your time away, like it does with me, but do go to Liturgy. Now I'm at my summer break and I'm spending it by burning my to-read list and subtitling Orthodox documentaries. If you are as well, try doing the same.
The more depraved our secular lives become the more striking the liturgical beauty is, please don't stop going to it.
I too feel that the fight is hopeless and that the end is near.
So let's pretend we did know for a fact that all is lost, which I believe we can not know for certain. Constantine XI, when he realized the turks had breached the wall, tore off his imperial regalia (so he could fight to the death) and ran head first into the wall breach. I think this is what a Christian must do in a lost scenario, just attack of the dead men it. Because, for one, you will never know for certain that all is lost, And two: if it is, fighting is STILL the correct thing to do.
The real cold water is not it being lost, it's that our lives won't be flashy and remembered. Accepting that is very humbling. Ours most likely will be a life of failed expectations and anonymity. We must keep on with all our might, however little it is. It's the life we must choose.
