My interpretation of the lyrics:

The "once in a lifetime" phrase likely refers to the supposed "once in a lifetime" economic recession that happened in the US in the late 1970s and early 1980s.

The song is kind of sarcastically pointing to the fact that this isn't just a once in a lifetime thing and has happened before and will happen again, (same as it ever was) causing many people to feel stuck with their life going nowhere:

Letting the days go by, Let the water hold me down

You get caught up in the process of life, trying to reach seemingly unachievable dreams, becoming depressed when you never seem to get any closer to them:

Into the blue again, into the silent water

It also may refer to the fact that you only get one life to live, and some opportunities only come by once in a lifetime.

Time neither slows down for you, nor does it try to catch up to you and make things go by faster for you:

Time isn't holding up, time isn't after us

don't quote me on these though 🌚

I feel like shit and I'm bored out of my fucking skull.

تا اطلاع ثانوی، عمیقاً و شدیداً کیرم تو این تابستون.

من همیشه کیرم تو تابستونه البته، ولی امسال دیگه نوبره.

mood

I'm supposed to smile and ignore it
Better than some

High roads are to fall from
Already hung

I'm pretty done
Once a favored son

I'm pretty done
Slap me 'round for fun

همون ترم 6 باید در اوج خداحافظی میکردم =))

IT'S RAINING

In the fields, the bodies burning
As the war machine keeps turning
Death and hatred to mankind
Poisoning their brainwashed minds
Oh, Lord, yeah

Politicians hide themselves away
They only started the war
Why should they go out to fight?
They leave that role to the poor, yeah

We're still dealing with the same shit. Even worse now.
