okay, from the lyrics

Everyone is convinced
that that "thing" they're searching
for is in the future.


It's saying that many of us waiting for happier and success future

But how many people have realized
that "it" is actually in the past?
I can't even guess.

but also many of us understood that there would be no miracle in the future, because we missed it in the past or missing in present

I saw the end of an era
with my own eyes.
But I didn't want to know
that it's my turn next.

I think that in chorus she's saying that realized other people hopes(for happier future)
but she also hopes for that one
or you may understand it literally like all people degrade, and she doesn't want to know that society would make her degrade too
other idea - she sees broken hopes of people, but it's scaring for her to realize that she also missed what she is looking for in the past

If, after simplifying it
a bit more, you think that "it"
merely connects and arranges memories,
then wouldn't everyone
already have "it?"
I want you to realize that.

If you would stop and think what are you looking for, and what for you live through today you would realize that you already have this thing, and you're livin with this already, but you won't mention it until you lose it

I saw the end of an era
with my own eyes.
And in truth, I actually
do know that it's my turn next.

she is saying that thing she doesn't have more understanding that other people does, and she is also even realizing that all she may need already present but anyway waiting for something in the future

You'll find me, won't you?
I'm betting that
you'll find me.

She is saying that thing(man) she is waiting for in the future, and she hopes in the future they will be together


Sorry if i'm wrong, choruses confused me, but i'm sure for verses))
