This is one of those questions that Jesus Himself said He didn't know the answer to.
We could quote Scripture forever: thief in the night and all that.
But I think fundamentally, every Christian and certainly nearly every generation of Christians including Orthodox throughout time thought they were in the last times.
And they all were right.
Poppy, I like your straight talk style and chutzpah to ask difficult questions and call BS on what you think are tepid answers.
So we have two ways of addressing as I can see:
A Poppy like answer, which are probably the best:
Don't worry about, just lead your life as if tomorrow or better yet the next moment will be your last on this planet.
Or unfortunately a more "sophisticated" answer, which are probably least helpful:
Our relationship with God to the degree we have one is apocalyptic by nature: revelatory. We are in the end times. History ended on the Cross. Christ's death perfected, finished, fulfilled, all that came before.
We as Christians, to the degree we have a relationship with God and are honest, are living the shadows of the age which is over and living in the age which has been coming, is coming, and is yet to come.
Christ is here, Christ is coming, Christ is yet to come.
In fact, during the DL, the fulness of time is celebrated as if all has been accomplished, from beginning to the rule of Christ over all and all, because the Orthodox Church is THE Catholic Church, which means every parish celebrating the Divine Liturgy is absolutely "complete". Every saint or holy person from the beginning of time, now, and those to come are present, as are all the myriads of noetic beings, and God the Father, the Son, and the Holy Spirit.
The Divine Liturgy is a celebration and partaking in that age to come in its fulness.
Christ has come in His second coming and He has not and He is on His way.
The Divine Liturgy among other things ought to serve as a wake up call (see Gethsemane) about this fact for Orthodox. Orthodox claim to have the fulness of faith, which ain't a list things to believe, but that they truly know through experience what the end of the old age is and what the new age is to be.
They are the Epistles to those living in the age that is fading of this truth. That ought to be very sobering.
Lord have mercy on them!
